Algebra-1

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

1.Arithmetic Sequence:

Calculate the differences between consecutive terms:

-18 - 6 = -24

54 - (-18) = 72

-162 - 54 = -216

The differences are not constant, so the sequence is not arithmetic.

2.Geometric Sequence:

Calculate the ratios between consecutive terms:
