How does one identify Fibonacci number?
The Fibonacci Sequence is the series of numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34….The next number is found by adding up the two numbers before it:
- the 2 is found by adding the two numbers before it (1+1),
- the 3 is found by adding the two numbers before it (1+2),
- the 5 is (2+3),
- and so on!

Which is not a Fibonacci number?
With the exceptions of 1, 8 and 144 (F1 = F2, F6 and F12) every Fibonacci number has a prime factor that is not a factor of any smaller Fibonacci number (Carmichael’s theorem). As a result, 8 and 144 (F6 and F12) are the only Fibonacci numbers that are the product of other Fibonacci numbers OEIS: A235383.

How do you calculate Fibonacci numbers?
The key Fibonacci ratio, 61.8 percent, is found by dividing one number in the series by the number that follows it. For example: 55 / 89 = 0.6179. The 38.2 percent ratio divides one number in the series by the number two places to the right. For example: 55 / 144 = 0.3819.
