Answer: The Fibonacci sequence is a numerical pattern that can appear in many living things. It was first described in the 12th century by the Italian Leonardo Finonacci.
It is an infinite sequence that begins with 0 and 1. The sequence is completed with the sum of the previous 2 numbers.
Following this logic, we can assemble the sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144 and so on.
This sequence is very common in nature and can be observed in many living things, such as insects, plants, the human face, even a chameleon's tail.
For example in a shell.
