Complete the pattern puzzles with alphabet letters on this fun preschool worksheet.

Let’s look at each row one by one to find the pattern and figure out what letter should come next.

---

Row 1: A B C B A B _

Look at the sequence:
A → B → C → B → A → B → ?

It looks like it’s going forward then backward:
A, B, C (forward)
then B, A (backward)
then B again... so maybe it’s repeating a pattern?

Actually, let’s see if it’s symmetric or has a cycle.

Another way:
Positions:
1: A
2: B
3: C
4: B
5: A
6: B
7: ?

If we think of it as a palindrome or mirror:
A B C B A — that’s symmetric around C. Then it starts again with B? Maybe the pattern is “ABCBA” repeated? But after ABCBA, it goes B — which is the second letter of ABCBA.

Wait — perhaps it’s “ABCBA” then “B” again? That doesn’t fit.

Alternative idea: Maybe it’s a wave: up to C, down to A, then up again?

From position 1-5: A B C B A — that’s a full wave. Then position 6 is B — which would be the start of the next wave? So position 7 should be C?

Yes! Let’s test:

Wave 1: A B C B A
Wave 2: B C B A ... but we only have B so far.

Actually, maybe the pattern is: A B C B A B C B A ...

So after A B C B A, it repeats starting from B? That seems messy.

Wait — let’s count positions:

1: A
2: B
3: C
4: B
5: A
6: B
7: ?

Notice that positions 1,5 are A; 2,4,6 are B; 3 is C.

Maybe it’s centered on C, and mirrors? But position 6 is B, which matches position 4.

Perhaps the pattern is: A B C B A, then B C B A ... no.

Another approach: Look at differences.

From 1 to 3: A→B→C (increasing)
3 to 5: C→B→A (decreasing)
5 to 6: A→B (increasing again)
So 6 to 7 should be B→C? Yes!

So the pattern is: go up to C, down to A, then up again.

So after A (pos5), B (pos6), next should be C (pos7).

✔ So Row 1: C

---

Row 2: J K L L K J _

Sequence: J, K, L, L, K, J, ?

This looks symmetric: J K L | L K J

It’s a palindrome: reads same forward and backward.

So after J, what comes next? If it’s repeating the pattern, maybe it starts over? But the pattern is 6 letters: JKL LKJ — that’s 6 letters.

Position 7 would be the start of the next cycle? So J?

But let’s check: if it’s a palindrome, and it ends at J (position 6), then position 7 should be the same as position 1, which is J.

Alternatively, maybe it’s meant to be a continuous palindrome? But palindromes don’t usually continue like that.

Wait — perhaps it’s “JKLLKJ” and then it repeats? So next is J.

But let’s see the structure:
Positions 1-3: J K L
Positions 4-6: L K J — which is reverse of 1-3.

So it’s a mirror: first half, then reverse.

Then position 7 should start the next set? So J again.

Yes, that makes sense.

✔ So Row 2: J

---

Row 3: S T T U T T _

Sequence: S, T, T, U, T, T, ?

Look at it: S T T | U T T | ?

It seems like “STT” then “UTT” — so the middle letter changes: S, then U.

What comes after U? Maybe W? Or back to S?

But let’s see the pattern:
First group: S T T
Second group: U T T
So the first letter increases: S → U (skip T?) — S, T, U — so next might be W? But that’s not consistent.

Alternatively, maybe it’s symmetric around U?

Positions:
1: S
2: T
3: T
4: U
5: T
6: T
7: ?

If it’s symmetric around position 4 (U), then position 3 and 5 are both T, position 2 and 6 are both T, so position 1 and 7 should be the same? Position 1 is S, so position 7 should be S.

Yes! That fits.

Symmetric: S T T U T T S

✔ So Row 3: S

---

Row 4: X Y Z X Y Z _

Sequence: X, Y, Z, X, Y, Z, ?

This is clearly repeating every 3 letters: XYZ XYZ ...

So after XYZ, next should be X.

✔ So Row 4: X

---

Row 5: K L M K L M M

Sequence: K, L, M, K, L, M, M

Wait — this one is different.

Positions:
1: K
2: L
3: M
4: K
5: L
6: M
7: M

The first six letters are “KLM KLM” — so repeating every 3.

Then position 7 is M — which is the same as position 6.

But why? Maybe it’s a mistake? Or perhaps the pattern changes?

Wait — let’s read carefully: “K L M K L M M”

After two full sets of KLM, it adds an extra M?

But the instruction is to complete the pattern puzzles — so we need to find what comes next after the given sequence.

Given: K L M K L M M — that’s 7 letters shown, and we need the 8th? No — looking back at the image description, each row has 6 letters shown and one blank at the end.

Wait — in the original problem, each row has 6 letters and one box to fill.

But in Row 5, it says: “K L M K L M M” — that’s 7 characters? That can’t be right.

Let me re-read the user’s input:

> K L M K L M M

That’s 7 items. But in the image, probably it’s 6 letters and one blank.

Perhaps it’s a typo in my reading.

Looking back at the original text:

> K L M K L M M

Wait — maybe it’s “K L M K L M” and then the blank is for the 7th, but it says “M” at the end? That doesn’t make sense.

Perhaps in the image, Row 5 is: K L M K L M [blank]

And the “M” at the end is part of the sequence? No.

Let me count the letters in the user’s message:

"K L M K L M M" — that’s 7 letters.

But in the context, each row should have 6 letters and one blank to fill.

Perhaps it’s a mistake, and it’s supposed to be "K L M K L M" with blank after.

But the user wrote "K L M K L M M" — maybe the last M is the answer? No, the task is to complete the pattern.

Another possibility: perhaps the sequence is K L M K L M, and then the next is M? But why?

Let’s assume that Row 5 is: K, L, M, K, L, M, and we need the 7th letter.

The pattern is repeating KLM every 3 letters.

So after K L M K L M, the next should be K.

But the user wrote "K L M K L M M" — which might be a error.

Perhaps in the image, it's "K L M K L M" and the blank is after, and the "M" is not there.

I think there might be a transcription error.

Looking back at the initial problem statement:

> K L M K L M M

But in standard such worksheets, each row has a fixed number of letters before the blank.

In Row 1: A B C B A B — 6 letters, blank after.

Similarly, Row 2: J K L L K J — 6 letters.

Row 3: S T T U T T — 6 letters.

Row 4: X Y Z X Y Z — 6 letters.

Row 5: should be 6 letters, then blank.

But "K L M K L M M" has 7 items.

Perhaps it's "K L M K L M" and the last "M" is a typo, or perhaps it's "K L M K L M" and we need to fill the 7th.

But in the sequence given, if it's K L M K L M, then next is K.

However, the user included "M" at the end, which might be the 7th letter already filled, but that doesn't make sense for the task.

Another idea: perhaps the pattern is K L M repeated, but the last letter is doubled or something.

Let's list the positions for Row 5 as given:

1: K
2: L
3: M
4: K
5: L
6: M
7: M — but this is the 7th, and we need the 8th? But the worksheet likely has only one blank per row.

I think there's a mistake in the input.

Perhaps in the image, Row 5 is "K L M K L M" with a blank after, and the "M" at the end is not part of it.

To resolve this, let's assume that the sequence is "K L M K L M" and we need the next letter, which should be K, as it's repeating every 3.

But the user wrote "K L M K L M M", which might mean that the 7th letter is M, and we need the 8th.

But that seems unlikely.

Perhaps the pattern is K L M, then K L M, then M — but that doesn't help.

Another thought: maybe it's "K L M" repeated, but the last group is incomplete, and it's "K L M" again, but only M is shown, so we need to fill the next.

I think the safest assumption is that Row 5 is meant to be "K L M K L M" with a blank after, so the next letter is K.

But let's double-check the user's input:

"K L M K L M M"

Perhaps it's "K L M K L M" and the last "M" is a separator or something, but that doesn't make sense.

Maybe it's a different pattern.

Let's look at the sequence: K, L, M, K, L, M, M

If we consider that after two full cycles, it adds an extra M, then the next might be K or L.

But that's speculative.

Perhaps the pattern is that the last letter is repeated: after K L M K L M, it adds M, so the sequence is K L M K L M M, and now we need the next, which could be K to start over.

But why repeat M?

Another idea: perhaps it's a mistake, and it's supposed to be "K L M K L M" with blank, and the "M" is not there.

Given that all other rows have 6 letters before the blank, I'll assume Row 5 is "K L M K L M" and we need the 7th letter, which is K.

But to be precise, let's see the pattern: positions 1,4 are K; 2,5 are L; 3,6 are M; so position 7 should be K, as it's the start of the next cycle.

Yes.

So for Row 5, if the sequence is K L M K L M, then next is K.

But the user wrote "K L M K L M M", which might include the 7th letter as M, but that would be inconsistent.

Perhaps in the image, the last letter is not M, but the blank is after 6 letters.

I think for the sake of solving, I'll go with K for Row 5.

But let's confirm with the symmetry or other logic.

Perhaps the pattern is that it's KLM repeated, and the blank is for the next in sequence.

So after K L M K L M, next is K.

✔ So Row 5: K

But wait, the user's input has "M" at the end, so if the sequence is given as K L M K L M M, then the 7th letter is M, and we need the 8th.

In that case, what is the pattern?

Positions:
1: K
2: L
3: M
4: K
5: L
6: M
7: M

So after two KLM, it has an extra M.

Then the next might be K, to start over, or L, or M.

But that seems arbitrary.

Perhaps the pattern is that the last letter of each group is repeated, but in the first group, M is not repeated, only in the second.

This is confusing.

Another possibility: maybe it's "K L M" then "K L M" then "M" as the beginning of the next, but incomplete.

I think the most reasonable assumption is that the sequence is meant to be "K L M K L M" with a blank after, and the "M" at the end is a typo or miscommunication.

In many such worksheets, the pattern is clear repetition.

So I'll go with K for Row 5.

To match the format, let's list all answers.

From above:

Row 1: C
Row 2: J
Row 3: S
Row 4: X
Row 5: K

But for Row 5, if the sequence is K L M K L M, then next is K.

If the sequence includes the 7th letter as M, then we need the 8th, which might be K.

Same answer.

So final answers per row:

1. C
2. J
3. S
4. X
5. K

Now, to present the final answer as per the format.

The task is to complete each pattern, so the answers are the letters for the blanks.

Final Answer:
C, J, S, X, K
