Algebra-1

To determine if the sequence is arithmetic, geometric, or neither:

1.Arithmetic Sequence:

Calculate the differences between consecutive terms:

-32 - 8 = -40

128 - (-32) = 160

-512 - 128 = -640

The differences between consecutive terms are -40, 160, and -640, which are not constant. Thus, the sequence is not arithmetic.

2.Geometric Sequence:

Calculate the ratios between consecutive terms:
