What is the Fibonacci series?

The Fibonacci series

A well-known series of numbers which is used in mathematics is the Fibonacci series, which is formed as follows:

a) The succession starts with two "ones".

b) You can get any number by adding the previous two numbers. So, if you add the 7th and the 8th number in the series, you will get the 9th.

c) The series is infinite.

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

Golden proportion

If we draw a parallel line (AB) and then we draw one point (C) somewhere on the line, so that the result of dividing AC/AB is the same as the result we get when we divide CB/AC, we obtain what is known as a Golden ratio.

the point C makes a golden section in the rectiline segment AB if AC/AB=CB/AC.
