Question

Please help!! Will give medal!
Generate the first 5 terms of this sequence
F(1)=2 and f(2)=3, f(n) =f (n-1)+f(n-2), for n>2
A. 2,3,5,7,9
B. 2,3,4,7,11
C. 2,3,5,9,11
D. 2,3,5,8,13

Answer 1

Well, to find the 3rd term, n = 3, you'd want f(3-1) + f(3-2) and that would be your 3rd term in the sequence. Continuing from there, the 4th would be f(4-1) + f(4-2).

In essence, check what the sequence is asking for :). f(2) + f(1) = f(3)

You are given f(2) and f(1). So what is f(2) + f(1) ?

Answer 2

f(3)=f(1)+f(2)=2+3 =5;
f(4) = f2+f3=3+5 = 8;
f(5) = f4+f3 =8+5 = 13;
ans d) @WhiteFlower :D

Answer 3

+1 for right answer, -1 for not stepping her through the concept :P @princeharryyy

Answer 4

Do you think you can help me? @princeharryyy

Answer 6

maybe @Ccarey24

Answer 7

That's easy for us to understand, but she might not know what it meant. Best bet is to always explain how and why. Excellent job showing steps though. :)
