If f(1)=6 and f(n) = F(n - 1) + 2 then find the value of f(4).
Usimov [2.4K]

Hi there!

\large\boxed{f(4) = 12}

We know that:

f(1) = 6

F(n) = F(n - 1) + 2 (Meaning, the next "n" is 2 added to the previous)

We can count up to f(4) using this logic:

f(2) = F(2 - 1) + 2 = F(1) + 2 = 6 + 2 = 8

f(3) = F(2) + 2 = 8 + 2 = 10

f(4) = F(3) + 2 = 10 + 2 = 12
