Question

What is the next term of the geometric sequence?
72,36, 18,

Answer 1

9.

Explanation:

The common ratio = 36/72 = 18/36 = 1/2.

So the next term is 18 * 1/2 = 9.

Answer 2

9

Explanation:

To find the common ratio, take the second term and divide by the first

36/72 = 1/2

To find the next term, take the last term and multiply by the common ratio

18*1/2 = 9
