You have artistic license when it comes to defining the first numbers in a sequence. Sometimes by playing around with them you get cool results.

One of the interesting things about the Fibonacci sequence is that the ratios of successive numbers such 8/5, 13/8, 21/13, etc, approach the famous irrational number known as Phi , associated with the Golden Ratio. But what's even more interesting, is that no matter how you define the first two numbers in the Fibonacci sequence -- suppose your sequence begins 7, 8, 15, 23, 38... -- the ratios of consecutive numbers will still converge on this value 1.61803399. You can even begin with 0 and 7, ensuring a Fibonacci-esque sequence whose members are all multiples of seven, and the ratios of successive numbers in the list will converge to Phi.
