Fibonacci Numbers are a string of numbers created by starting with the two consecutive numbers 0 and 1. Add them together and you get 1.
Now you have the string 0, 1, 1.
Add the last two numbers of the string together and you get 2.
Now you have the string 0, 1, 1, 2.
Add the last two numbers of the string together and you get 3.
Now the string is 0, 1, 1, 2, 3.
Keep going and you find the string 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144 . . .
