Let’s solve each number pattern step by step. We’ll look at how the numbers change from one to the next, then continue that same rule for the missing numbers.

1. 1, 3, 5, 7, 9, ___, ___, ___ ...
Look:
3 - 1 = 2
5 - 3 = 2
7 - 5 = 2
9 - 7 = 2
→ Rule: Add 2 each time.
Next:
9 + 2 =
11
11 + 2 =
13
13 + 2 =
15
---
2. 2, 4, 6, 8, 10, ___, ___, ___ ...
Look:
4 - 2 = 2
6 - 4 = 2
8 - 6 = 2
10 - 8 = 2
→ Rule: Add 2 each time.
Next:
10 + 2 =
12
12 + 2 =
14
14 + 2 =
16

3. 24, 34, 44, 54, ___, ___, ___ ...
Look:
34 - 24 = 10
44 - 34 = 10
54 - 44 = 10
→ Rule: Add 10 each time.
Next:
54 + 10 =
64
64 + 10 =
74
74 + 10 =
84
---
4. 3, 6, 9, 12, 15, ___, ___, ___ ...
Look:
6 - 3 = 3
9 - 6 = 3
12 - 9 = 3
15 - 12 = 3
→ Rule: Add 3 each time.
Next:
15 + 3 =
18
18 + 3 =
21
21 + 3 =
24
---
5. 35, 40, 45, 50, ___, ___, ___ ...
Look:
40 - 35 = 5
45 - 40 = 5
50 - 45 = 5
→ Rule: Add 5 each time.
Next:
50 + 5 =
55
55 + 5 =
60
60 + 5 =
65
---
6. 11, 22, 33, 44, ___, ___, ___ ...
Look:
22 - 11 = 11
33 - 22 = 11
44 - 33 = 11
→ Rule: Add 11 each time.
Next:
44 + 11 =
55
55 + 11 =
66
66 + 11 =
77
---
7. 9, 19, 29, 39, ___, ___, ___ ...
Look:
19 - 9 = 10
29 - 19 = 10
39 - 29 = 10
→ Rule: Add 10 each time.
Next:
39 + 10 =
49
49 + 10 =
59
59 + 10 =
69
---
Final Answer:
1. 11, 13, 15
2. 12, 14, 16
3. 64, 74, 84
4. 18, 21, 24
5. 55, 60, 65
6. 55, 66, 77
7. 49, 59, 69
