Homework Statement
A>0, B can be any number
Homework Equations
To show that
lim(n->∞) (1/n)log[A((1+sqrt(5))/2)^n +B((1-sqrt(5))/2)^n] = (1+sqrt(5))/2
The Attempt at a Solution
I used Lhopital's Rule to solve this and got
log((1+sqrt(5))/2)
So, I don't know what is wrong.
If you guys know how to prove this one, please let me know.
Thanks a lot
