The Fibonacci Sequence
is formed by adding the latest two numbers to get the
next one, starting from 0 and 1:

0 1 --the series starts like this.
0+1=1 so the series is now
011
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 ...
