Question

The explicit formula for the geometric sequence -11 -1,3 - 9,... is f(x) = - 1(-3)^x- 1. What is the common ratu

and recursive formula for this sequence?
3; f(x + 1) = 3(f(x))
-3; f(x + 1) = -3(f(x))
3; f(x+ 1) = 1/3(f(x))
-3; f(x+1) = 1/3(f(x))

Answer 1

Answer: It's B!

Explanation:

Answer 2
