What is the rule for the following geometric sequence? 64, -32,16,-8

Answer 1

The rule is n/(-2)

What is geometric Progression?

A geometric progression is a sequence in which any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r.

Given:

64, -32,16,-8

r= 64/-32

r= -2

again, r= -32/16

r= -2

By above we concluded that the common ratio is is -2.

If n is natural numbers for finding geometric progression the rule which defines it n/(-2).
