Question

Find f(5) for this sequence:

f(1) = 2 and f(2) = 5, f(n) = f(1) + f(2) + f(n - 1), for n > 2.

f(5) = ______

Answer 1

first can you find f(3)?

Answer 2

Answer 3

No, I suck at math

Answer 4

well
f(n)=f(1)+f(2)+f(n-1)
f(1) is 2 so I'm going to replace f(1) with 2
f(2) is 5 so I'm going to replace f(2) with 5
so we can write f(n) as
f(n)=2+5+f(n-1)
f(n)=7+f(n-1)<---we will just use this

Answer 5

To find f(3) you need to replace the n's with 3's

Answer 6

can you do that?
