0 1 --the series starts like this. 0+1=1 so the series is now 0 1 1 1+1=2 so the series continues... 0 1 1 2 and the next term is 1+2=3 so we now have 0 1 1 2 3 and it continues as follows ...

On these pages, the first Fibonacci number is 1, as is the second, the third being 2, the fourth 3 and so on. We will often include Fib(0)=0 too:

n: | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | ... |
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

Fib(n): | 0 | 1 | 1 | 2 | 3 | 5 | 8 | 13 | 21 | 34 | 55 | 89 | 144 | 233 | 377 | 610 | 987 | ..More.. |
