The task involves solving addition problems using the numbers provided in the circular diagrams. Each diagram has a central number that needs to be added to the numbers around the circle. Let's solve each problem step by step.

---

Problem 1:

Central number: 5
Numbers around the circle: 1, 4, 2, 16, 10, 7, 5, 13

#### Solution:
- \( 5 + 1 = 6 \)
- \( 5 + 4 = 9 \)
- \( 5 + 2 = 7 \)
- \( 5 + 16 = 21 \)
- \( 5 + 10 = 15 \)
- \( 5 + 7 = 12 \)
- \( 5 + 5 = 10 \)
- \( 5 + 13 = 18 \)

Answers for Problem 1:
6, 9, 7, 21, 15, 12, 10, 18
