Use the recursive formula f(n) = 0.4 . f(n-1) + 12 to determine the 2nd term if f(1) = 4.

Irina18 [472]

Answer:

Assuming you have $f(n)=0.4f(n-1)+12$ with $f(1)=4$ , the answer is f(2)=13.6.

Step-by-step explanation:

I think that says $f(n)=0.4f(n-1)+12$ with $f(1)=4$ .

Now we want to find $f(2)$ so replace n with 2:

This gives you:

$f(2)=0.4f(2-1)+12$

$f(2)=0.4f(1)+12$

$f(2)=0.4(4)+12$

$f(2)=1.6+12$

$f(2)=13.6$
