Let's solve the "Missing Numbers" problem step by step.
We are given sequences of numbers with some missing values. The goal is to
fill in the missing numbers based on the pattern.
---
1. Sequence: 1, __, 3, __, 5
- This sequence starts at 1 and ends at 5.
- We can see that it's increasing by
2 each time:
1 → 3 → 5
- So, the missing numbers should be:
- After 1:
2
- After 3:
4
✔ Completed:
1, 2, 3, 4, 5
---
2. Sequence: 6, __, 8, __, 10
- Starts at 6, ends at 10.
- Increasing by
2 each time:
6 → 8 → 10
- Missing numbers:
- After 6:
7
- After 8:
9
✔ Completed:
6, 7, 8, 9, 10
---
3. Sequence: 11, __, 13, __, 15
- Starts at 11, ends at 15.
- Pattern: increasing by
2
- So:
- After 11:
12
- After 13:
14
✔ Completed:
11, 12, 13, 14, 15
---
4. Sequence: 16, 17, __, 19, __, __
- Starts at 16, then 17 → so it's increasing by
1.
- Let’s go step by step:
- 16, 17,
18, 19,
20,
21
✔ Completed:
16, 17, 18, 19, 20, 21
---
5. Sequence: 21, __, 23, __, 25
- Starts at 21, ends at 25.
- Increasing by
2: 21 → 23 → 25
- So:
- After 21:
22
- After 23:
24
✔ Completed:
21, 22, 23, 24, 25
---
✔ Final Answer:
1.
1, 2, 3, 4, 5
2.
6, 7, 8, 9, 10
3.
11, 12, 13, 14, 15
4.
16, 17, 18, 19, 20, 21
5.
21, 22, 23, 24, 25

🔍 Explanation:
All sequences follow a simple
arithmetic pattern:
- Most increase by
1 or
2.
- By identifying the common difference between known numbers, we can fill in the blanks logically.
This kind of exercise helps build number sense and pattern recognition skills, especially for young learners.
