Question

Help Please!!
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.

Answer 1

let f(1)+f(2)= t = 7 then f(5)= t+f(4)
f(4)= t+f(3)
f(3)= t+(f(2)) just put the values

Answer 2

Umm... so it 4?

Answer 3

it's*

Answer 4

talking about answer?

Answer 5

Yes. Would the answer be f(5)=4n?

Answer 6

nope 26

Answer 7

Oh.. Okay
