Algebra-1

To determine which of the given sequences is geometric, we need to check if the ratio between consecutive terms is constant. A sequence is geometric if the ratio between any two consecutive terms is always the same.

Let’s analyze each sequence:

A. 

Calculate the ratios between consecutive terms:

The ratios are not consistent. This sequence is not geometric; it is arithmetic with a constant difference of 10.

B. 

Calculate the ratios between consecutive terms:

The ratios are
