Answer 2

Answer:

The common ratio of the geometric sequence = -2

Step-by-step explanation:

Given,

The geometric sequence 4,-8,16,-32

To find,

The common ratio of the geometric sequence

Solution:

The geometric sequence is a sequence in which the ratio between two consecutive terms is a constant. This constant is called the common ratio.

It is denoted by the letter 'r'

r = $\frac{second \ term}{ first \ term}$

The second term = -8

The first term = 4

The common ratio = $\frac{-8}{4} = 2$

The common ratio of the geometric sequence = -2
