Printable number sequence worksheet for practicing pattern recognition and arithmetic skills.

Let’s go through each number sequence one by one. We’ll look at how the numbers change from one to the next — that’s the pattern!

---

1. 2, 4, 6, 8, ___, ___

Look:
4 - 2 = 2
6 - 4 = 2
8 - 6 = 2

So we’re adding 2 each time.

Next two numbers:
8 + 2 = 10
10 + 2 = 12

Pattern: Add 2

---

2. 3, 6, 9, 12, ___, ___

6 - 3 = 3
9 - 6 = 3
12 - 9 = 3

Adding 3 each time.

Next:
12 + 3 = 15
15 + 3 = 18

Pattern: Add 3

---

3. 115, 120, 125, 130, ___, ___

120 - 115 = 5
125 - 120 = 5
130 - 125 = 5

Adding 5 each time.

Next:
130 + 5 = 135
135 + 5 = 140

Pattern: Add 5

---

4. 1050, 1060, 1070, ___, ___

1060 - 1050 = 10
1070 - 1060 = 10

Adding 10 each time.

Next:
1070 + 10 = 1080
1080 + 10 = 1090

Pattern: Add 10

---

5. 10, 9, 8, 7, ___, ___, ___

9 - 10 = -1 → going down by 1
8 - 9 = -1
7 - 8 = -1

Subtracting 1 each time.

Next:
7 - 1 = 6
6 - 1 = 5
5 - 1 = 4

Pattern: Subtract 1

---

6. 2075, 2050, 2025, ___, ___

2050 - 2075 = -25
2025 - 2050 = -25

Subtracting 25 each time.

Next:
2025 - 25 = 2000
2000 - 25 = 1975

Pattern: Subtract 25

---

7. 850, 841, 832, ___, ___, ___

841 - 850 = -9
832 - 841 = -9

Subtracting 9 each time.

Next:
832 - 9 = 823
823 - 9 = 814
814 - 9 = 805

Pattern: Subtract 9

---

Final Answer:

1. 2, 4, 6, 8, 10, 12 → Pattern: Add 2
2. 3, 6, 9, 12, 15, 18 → Pattern: Add 3
3. 115, 120, 125, 130, 135, 140 → Pattern: Add 5
4. 1050, 1060, 1070, 1080, 1090 → Pattern: Add 10
5. 10, 9, 8, 7, 6, 5, 4 → Pattern: Subtract 1
6. 2075, 2050, 2025, 2000, 1975 → Pattern: Subtract 25
7. 850, 841, 832, 823, 814, 805 → Pattern: Subtract 9
