Math Help - Lots of questions

1. Lots of questions

Help!!!!
Let fn+1 = 2fn – fn-1. Where f0 = 2 and f1 = 1.
I need to compute each of the following:

f2, f3, f4, f5

f2 =

f3 =

f4 =

f5 =

Let's do one, and you do the rest:

$f_2=f_{1+1}=2f_1-f_0=2-2=0$

Likewise, $f_3=f_{2+1}=2f_2-f_1=$...

3. I got the rest. Thank you for your gracious help.
