Question

(PLEASEEEE HELP)Which of the following is a geometric sequence with a common ratio of 2?

A. 14, 16, 18, 20, ...
B. 14, 28, 56, 112, ...
C. 87, 85, 83, 81, ...
D. 64, 32, 16, 8, ...

Answer 1

B.

Explanation:

A geometric sequence is a exponential sequence, meaning that it has a common ratio, not a common difference. A common ratio of 2 would be that you multiply the next number by 2.

So......

14*2=28

28*2=56

56*2=112
