Question

Find the common ratio r for the given geometric sequence and find the next three terms.

Answer 1

Answer:

A -0.5

B 4.5, -2.25, 1.125

Step-by-step explanation:

A: 72× -0.5= -36

-36× -0.5= 18

18× -0.5= -9

B multiple everything by -0.5

Answer 2

Answer:

The common ratio is -2

Next three terms are 18, -36, and 72

Step-by-step explanation:

The common ratio is -2 since each consecutive term is being multiplied by -2

The next three terms are -9(-2) = 18, 18(-2) = -36, and -36(-2) = 72
