Recall that the Fibonnaci numbers are generated by the sequence

$x_0=1,x_1=1,x_{n+1}=x_n+x_{n-1}$ for $n1.$

a$.$ Write a MATLAB script used to evaluate the first $N$ Fibonnacci numbers for any $N.$ Copy$/$paste you script below.

b$.$ Use your script to estimate $\underset{n}{lim}\frac{x_{n+1}}{x_n}.$
