Question

Use the recursive formula f(n) = 0.4 ⋅ f(n − 1) + 11 to determine the 2nd term if f(1) = 4.

A.f(2) = 11.8
B.f(2) = 12.2
C.f(2) = 12.6
D.f(2) = 13

Answer 1

Answer:

C.f(2) = 12.6

Step-by-step explanation:

f(n) = 0.4 ⋅ f(n − 1) + 11

f(1) = 4

Let n=2

f(2) = .4 f(1) +11

      = .4 (4) +11

      = 1.6 +11

       = 12.6

Answer 2

Answer:

c-12.6

Step-by-step explanation:

Use the formula and substitute the n for the value and u will find it.
