Question

Which sequence below represents an exponential sequence A.) {2,6,10,14,18,...} B.) {3,5,9,16,24,...} C.) {4,8,24,96,...} D.) {256,64,16,4,...}

Answer 1

D.) {256,64,16,4,...}

Explanation:

Look for the sequence in which adjacent terms are related by a common ratio.

A. 10/6 ≠ 6/2

B. 9/5 ≠ 5/3

C. 8/4 ≠ 24/8

D. 64/256 = 16/64 = 4/16 = 1/4 . . . . this exponential sequence has a common ratio of 1/4
