What is the recursive formula of the geometric sequence? 1, 5, 25, 125, 625, ... answers
A)

an = (1) ⋅ (1∕5)n – 1 for n ≥ 1

B)

a1 = 5; an = an – 1 ⋅ (1) for n ≥ 2

C)

an = (1) ⋅ (5)n – 1 for n ≥ 1

D)

a1 = 1; an = an – 1 ⋅ (5) for n ≥ 2

all I know is that it should be c but I don't an explanation.

all it means is function 3

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
