# Fibonacci Sequence

The numbers of the Fibonacci Sequence can either start 0,1, or 1,1, depending on the author. However, beyond that everyone agrees, so: 0, 1, 1, 2, 3, 5, 8, 13, …

With this sequence we add the 2 previous numbers to get the current number. The general term of this sequence is

$a_{n}=a_{n-1}+a_{n-2}$

Do not let the name fool you, it was not ‘invented’ by Fibonacci. The sequence has been used for centuries before him. Many contributors to the topic came after Fibonacci as well.
