In mathematics, the '''Fibonacci numbers''', commonly denoted <math>F_n</math>, form a sequence, called the '''Fibonacci sequence''', such that each number is the sum of the two preceding ones, starting from 0 and 1. That is,
:<math>F_0=0,\quad F_1= 1,</math>
and
:<math>F_n=F_{n-1} + F_{n-2},</math>
for <math>n > 1</math>.

The beginning of the sequence is thus:
:<math>0,\;1,\;1,\;2,\;3,\;5,\;8,\;13,\;21,\;34,\;55,\;89,\;144,\; \ldots</math>
