Let's solve each number pattern step by step and fill in the blanks correctly.

1. Pattern: 2, 4, 6, 8, 10, 12, 14, 18

Wait — there’s a jump from 14 to 18 (missing 16). But looking closely at the sequence:

- 2 → 4 (+2)
- 4 → 6 (+2)
- 6 → 8 (+2)
- 8 → 10 (+2)
- 10 → 12 (+2)
- 12 → 14 (+2)
- 14 → 18 (+4) ✘

This seems like a typo or mistake — likely 16 should be between 14 and 18.

But since the problem says "Complete the pattern" and the numbers are already filled in, we assume it's correct as is. However, the jump from 14 to 18 breaks the pattern.

But wait — let's check if it's possible that the pattern is counting by 2s, and the last number is a typo?

Let’s assume it's supposed to be:
2, 4, 6, 8, 10, 12, 14, 16, 18 — then it would be perfect.

But in the image, it shows:
2, 4, 6, 8, 10, 12, 14, 18 — so 16 is missing.

But maybe the question just wants us to describe what’s going on up to 14, and then the last number is 18? That doesn’t make sense.

Alternatively, perhaps it's intentional, but let’s recheck: maybe the pattern is not consistent?

Wait — actually, the pattern is counting by 2s, starting at 2.

So the full sequence should be:
2, 4, 6, 8, 10, 12, 14, 16, 18

But here, 16 is skipped, and 18 is shown instead.

That suggests either a typo in the worksheet, or perhaps the blank is meant to be filled in as even numbers.

But the instruction is: “We are counting ____ by ____'s; starting from ____ to ____”

Let’s analyze:

Even though 16 is missing, the numbers present are all even, increasing by 2.

So likely, the intended pattern is counting by 2s, starting from 2 to 18.

So for #1:
- We are counting even numbers by 2's, starting from 2 to 18

But technically, the pattern is counting by 2s, so we can say:

> We are counting by 2's, starting from 2 to 18

(Though 16 is missing — maybe it's a mistake.)

But since the problem gives the sequence as is, we’ll go with the intended pattern.

✔ So for #1:
- We are counting by 2's; starting from 2 to 18

2. Pattern: 4, 8, 12, 16, 20, 24, 28, 32

Check the differences:
- 8 - 4 = 4
- 12 - 8 = 4
- 16 - 12 = 4
→ All increase by 4

So this is counting by 4s, starting from 4 to 32

✔ So for #2:
- We are counting by 4's; starting from 4 to 32

---

3. Pattern: 5, 10, 15, 20, 25, 30, 35, 40

Differences:
- 10 - 5 = 5
- 15 - 10 = 5
→ Increasing by 5

So counting by 5s, from 5 to 40

✔ For #3:
- We are counting by 5's; starting from 5 to 40

---

4. Pattern: 10, 20, 30, 40, 50, 60, 70, 80

Differences:
- 20 - 10 = 10
- 30 - 20 = 10
→ Increasing by 10

So counting by 10s, from 10 to 80

✔ For #4:
- We are counting by 10's; starting from 10 to 80

---

✔ Final Answers:

1. We are counting by 2's; starting from 2 to 18
2. We are counting by 4's; starting from 4 to 32
3. We are counting by 5's; starting from 5 to 40
4. We are counting by 10's; starting from 10 to 80

⚠️ Note: In problem #1, the number 16 is missing between 14 and 18. If the sequence is truly:
2, 4, 6, 8, 10, 12, 14, 18, then the pattern breaks. But since the rest of the sequence increases by 2, and 18 is the last number, it's likely a typo — it should be 16 before 18.

However, based on the given numbers, the intended pattern is still counting by 2s, so we go with that.

✔ Summary:

| Problem | Pattern Type | Counting By | Start | End |
|--------|--------------------|-------------|-------|-----|
| 1 | Even numbers | 2's | 2 | 18 |
| 2 | Multiples of 4 | 4's | 4 | 32 |
| 3 | Multiples of 5 | 5's | 5 | 40 |
| 4 | Multiples of 10 | 10's | 10 | 80 |

All follow the rule: Counting by [number]'s from [start] to [end].
