Which of the following is not geometric sequence a. 2 10 50 250 1250 b. 1 1 2 3 5 8 13 21 c. 1 4 9 16 25 36 d. -4 -2 -1 -0.5 -0.25 -0..125

A. The common ratio is 5

B. The sequence is the Fibonacci sequence. There is no common ratio.

C. The sequence is a sequence of squares. There is no common ratio.

D. The common ratio is 1/2.

A and D are geometric sequences.

B and C are not geometric sequences.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
