Fibonacci sequence

A sequence of numbers where both previous numbers have to be added to get the next number is known as the Fibonacci sequence.

Here’s the sequence:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, …

Therefore, after 1 and 1, the next number is 1 + 1 = 2, the next number is 1 + 2 = 3, the next number is 2 + 3 = 5 and so on.

It’s named after Leonardo Bonacci, a mathematician from Italy, who was known as Fibonacci.
