## Description

Implement a function to find the Fibonacci sequence with Ruby

## Transcript

let's write a function in ruby to find the fibonacci sequence we're going to write this method here that will take in some number and that will return the number of items in the fibonacci sequence the fibonacci sequence is a very special set of numbers where any num in the set can be derived by adding the two previous numbers so here we can say five is equal to two plus three so we'll start with our base case and that is if we encounter n equals one then we wanna return an array with just one inside of it and we can do this implicitly in ruby otherwise if it's two we want to return an array with one and one now we're at our final case using the fibonacci sequence of n minus one and we can call that maybe fibs and we'll say the fibonacci sequence of n minus 1 and for the final item in the array we can add in the last item and the second to last item into our array before returning it we can run this with ruby fib and here we see 10 items in the fibonacci sequence
