#Fibonacci

This rails app is a test of the Fibonacci Number. It accepts an input and finds what nth Fibonacci sequence number is.

For example, if you would like to see what the third number of the Fibonacci sequence, you would add 0 + 1 to give you 1 then add the last number of the previous sequence (1) with the result of that last sequence (1), which gives you 2. Then finally 1 + 2 to give you 3.

To find the fourth, you would simply add 2 + 3 to get 5. And so on.

##Use of the Function

To use the fibonacci function, you simply add an input in the arguments. Example:

##Requirements

Input has to be a whole number higher than 0 (starting from 1).

fib(5)
>> 8
