2 answers
keep subtracting 8
7 - 15 = - 8
- 1 - 7 = - 8
- 9 - ( - 1 ) = - 9 + 1 = - 8
This is an arithmetic progression with common difference d = - 8
Next two term:
- 9 - 8 = - 17
- 17 - 18 = - 25
- 1 - 7 = - 8
- 9 - ( - 1 ) = - 9 + 1 = - 8
This is an arithmetic progression with common difference d = - 8
Next two term:
- 9 - 8 = - 17
- 17 - 18 = - 25
