In mathematics, Fibonacci numbers, commonly referred to as Fₙ, form a sequence, called the Fibonacci sequence, so that each number is the sum of the previous two, starting with 0 and 1.
So basically it’s a set of numbers that start at 0 and proceeds based on the rule that each number is equal to the sum of the proceeding 2 numbers like 0,1,1,2,3,5,8,13,21,34 and so on
