very hard math you can scroll down the list to see the Fibonacci sequence occur the formula is F(n)=F(n−1)+F(n−2) with initial conditions: F(0)=0,F(1)=1 this means that the current number will be added on to the old number to make the new number with the only exception being (0+0=1) you can scroll down the list to see the Fibonacci sequence occur
