The Fibonacci sequence can be written as a recurrence relation. Solve that relation for the nth term, and then form the desired ratio and take the limit. Does that give you some ideas?
any help on getting started would be great. i really don't know where to go with this as i'm useless with limits.
alpha is the golden ration ((1+sqrt5)/2)
f2k etc are part of the fibonacci sequence
prove lim f2k/f2k+1 = 1/alpha
k->infinity
