Question

Which of the terms best describes the following sequence?

162, 54, 18, 6, ...

Answer 1

Geometric sequence with a common ratio of 1/3

Explanation:

Each term is 1/3 of the previous term:
First term is : 162
Second term: 162 x 1/3 = 162/3 = 54
Third term : 54 x 1/3 = 54/3 = 18

and so on

The ratio of a term to its previous term is therefore 1/3 and this is called a common ration

This kind of sequence where each term is a multiple (1/3) of the previous term is called a geometric sequence
