Answer 1

Step-by-step explanation:

1. the sequence is an AP

d = -2

2. the sequence is an AP

d = 3

3. the sequence is not an AP

4. the sequence is an AP

d = -2

5. the sequence is not an AP

6. the sequence is an AP

d = 0.5

7. the sequence is an AP

d = 1/3

8. the sequence is not an AP

9. the sequence is not an AP

10. the sequence is not an AP
