Explanation

A sequence is geometric when the ratio between each term and the term before it stays the same. In A, each term is multiplied by about 3.33; in B, each term is multiplied by −2.5; and in C, each term is multiplied by 0.1. The ratios are constant in all three sequences, so A, B, and C are geometric.
