Is Fibonacci The golden ratio?
The golden ratio is derived by dividing each number of the Fibonacci series by its immediate predecessor. In mathematical terms, if F(n) describes the nth Fibonacci number, the quotient F(n)/ F(n-1) will approach the limit 1.618… for increasingly high values of n. This limit is better known as the golden ratio.
What is the 11th Fibonacci number?

Fibonacci series is the series with the 1st and 2nd term as 1, and the all the further terms obtained by adding the previous 2 terms. So, the series turns out be : 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233… As per the series, the 11th Fibonacci number is 89.
