Fibonacci

Fibonacci sequence or Fibonacci series is a series of Fibonacci numbers created by Leonardo Fibonacci. Leonardo Fibonacci noticed patterns of Fibonacci spiral all around him almost 800 years ago. The Fibonacci numbers in nature or Fibonacci sequence in nature fascinated Leonardo Fibonacci so much that he later described it mathematically.

Leonardo Fibonacci and the Fibonacci sequence

Almost 800 years ago, Italian mathematician LEonardo Fibonacci noticed that there were patterns all around him - in the petals of a flower, the branches or a tree, adn the speiral of a snail shell. In 1202 Leonardo Fibonacci discovered a way to describe these patterns through mathematics. Leonardo Fibonacci created a number series known as the Fibonacci sequence or Fibonacci series.

What does the Fibonacci numbers or Fibonacci series look like?

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ...

How to create a Fibonacci sequence and Fibonacci numbers?

To create Fibonacci series of Fibonacci numbers, each number except the first 1 is added to the number before itself. The sum becomes the next Fibonacci number in the Fibonacci series.

The first Fibonacci number in the Fibonacci sequence is 1

The second Fibonacci number in the Fibonacci sequence  is 1

The third Fibonacci number in the Fibonacci sequence is 1 + 1 = 2

The fourth Fibonacci number in the Fibonacci sequence  is 2 + 1 = 3

The fifth Fibonacci number in the Fibonacci sequence is 3 + 2 = 5

and so on...
