F(x + 1) = (5/2)*f(x)

f(x + 1) = 2.5*f(x), f(1) = 3.2

f(2) = 2.5f(1) = 2.5*3.2 = 8

<span>f(3) = 2.5f(2) = 2.5*8 = 20
</span>
f(4) = 2.5f(3) = 2.5*20 = 50

<span>f(5) = 2.5f(4) = 2.5*50 = 125</span>

Answer:

Step-by-step explanation:

Plug in 15 for y in the first problem so instead of y=x-11 it would be 15=x-11

15=x-11

+11= +11 (you want to add 11 to both sides to get x by its self)
