Use the recursive formula f(n) = 0.4 . f(n-1) + 12 to determine the 2nd term if f(1) = 4.
a. f(2) = 12.6
b. f(2) = 13.2
c. f(2) = 13.6
d. f(2) = 14.2

Assuming you have with , the answer is f(2)=13.6.

Step-by-step explanation:

I think that says with .

Now we want to find so replace n with 2:

This gives you:

13.6 (Answer C)

Step-by-step explanation:

I think you meant  f(n) = 0.4 * f(n-1) + 12, where * represents multiplication.

Then f(2) = 0.4 * (4) + 12, or 1.6 + 12, or 13.6.
