It is as follows:
Kind of a weird property as the operation on the top changes depending on the value of x.

Very interesting. I have always been fascinated by the fibonacci sequence and the divine ratio.

2 is Fibonacci number 4, and 1 is Fibonacci number 2 (and 3, but let's go with 2). Let's try it out:
(2)^2 + (-1)(1)^2 = 3. 3 / 1 = 3. Is 3 Fibonacci number (2*4 - 2)? Fibonacci number 6? No, 3 is Fibonacci number 5.
I 'dunno man, I think it doesn't hold up.

Just realized my stupidity. This equation has F1=1, F2=1, F3=2....so it starts with 1 and 1 and then goes onward instead of 0 and 1 as the first two terms. I'm working on a new equation that uses 0 and 1 as the first two. However, this equation does hold up when 1 and 1 are the first terms. When 1 and 1 are the first 2 terms, 2 is fib number 3 and 1 is number 1. Therefore the quotient should be 2*3-(3-1)=4, and 3 is indeed fib number 4 when 1 and 1 are the first terms of the sequence.
