fibonacci numbers - How to evaluate the series sumin=1nftyfrac1F4n? Where F1=1, F2=1 and Fn=Fn1+Fn2

How would I go about evaluating the following series: n=11F4n



Where F1=1, F2=1 and Fn=Fn1+Fn2 for n3



Not sure how to go about this except maybe by using the close form for the nth fibonacci number, but that seems like way too much arithmetic. Any ideas?
