Best ResponseYou've already chosen the best response.2questions relating to fibonacci sequence are fun indeed! try this when you're free : \[\large \lim\limits_{n\to\infty}\dfrac{F_{n+1}}{F_n} ~~=~~\phi\] where \(\phi\) is the golden ratio.

Best ResponseYou've already chosen the best response.0\[\lim_{n \to \infty } \frac{F_{n+1}}{F_n} = L \]\[= \lim_{n\to \infty} \frac{F_n}{F_n} + \lim_{n \to \infty} \frac{F_{n1}}{F_n}\]\[= 1 + \frac{1}{L}\]
