I need help understanding recursion and I also need to write a ruby function that takes a number X as an input parameter and returns the Xth number in a standard fibonacci sequence. For example, fib(5) would return 5 (1, 1, 2, 3, 5) and fib(7) would return 13.

Write a ruby function that takes a number X as an input parameter and returns the Xth number ina standard fibonacci sequence:Recursive Function :def fibo(number)return result = (number<2 ?...
