Algebra-1

To determine which sequence has a common ratio of 1/2, we need to check if each term is obtained by multiplying the previous term by 1/2.

Let's examine each sequence:

A. (4, 8, 16, ...): This sequence does not have a common ratio of 1/2. The ratio between consecutive terms is 8/4 = 2, not 1/2.

B. (12, 6, 3, ...): This sequence does not have a common ratio of 1/2 either. The ratio between consecutive terms is 6/12 = 1/2, but the ratio between the second and third terms is 3/6 = 1/2 as well. Therefore, the sequence does not have a consistent common ratio.

C. (4...
