fibonacci

Returns the nth number of the Fibonacci sequence.

Wikipedia:

In mathematics, the Fibonacci numbers, commonly denoted \(F_n\) , form a sequence, the Fibonacci sequence, in which each number is the sum of the two preceding ones. The sequence commonly starts from 0 and 1, although some authors omit the initial terms and start the sequence from 1 and 1 or from 1 and 2. Starting from 0 and 1, the next few values in the sequence are:

\(0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ...\)
