The random Fibonacci sequence is defined as follows: $$ f_n = \begin{cases} f_{n-1}+f_{n-2} \text{ with probability } 1/2 \\ f_{n-1}-f_{n-2} \text{ with probability } 1/2 \\ \end{cases} $$ $$ f_1 = f_2 = 1 $$ i.e. whether the next term is the sum or difference of the previous two is chosen at ra...
