+8 A^n= -4(-2)^n-1
Equation: Find "n" Term for -4,8,-16,32....
So since I would minus one from "n", will it be the third product or the fourth one? (Third: -16) (Fourth: 32)
So...
-4(-2)^4-1=
-4(-2)^3
-4(-8)=
32?
Is this how you would solve it?
P.S. Studying finals and having hard time on the easiest ones :3
