1. 2 + ___ + 7 = 14
First, add the known numbers:
- 2 + 7 = 9
Now subtract from the total:
- 14 - 9 =
5
✔ So, the missing number is
5.

2. 4 + ___ + 6 = 12
Add known numbers:
- 4 + 6 = 10
Subtract from total:
- 12 - 10 =
2
✔ Missing number is
2.

3. 3 + ___ + 4 = 11
Add known numbers:
- 3 + 4 = 7
Subtract from total:
- 11 - 7 =
4
✔ Missing number is
4.

4. 6 + ___ + 3 = 19
Add known numbers:
- 6 + 3 = 9
Subtract from total:
- 19 - 9 =
10
✔ Missing number is
10.

5. 8 + ___ + 5 = 15
Add known numbers:
- 8 + 5 = 13
Subtract from total:
- 15 - 13 =
2
✔ Missing number is
