Fibonacci Series is a series of numbers where the first two Fibonacci numbers are 0 and 1, and each subsequent number is the sum of the previous two. A Fibonacci sequence is one where every element is a sum of the previous two elements in the sequence. A series is defined in the following manner: Given the nth and (n+1)th terms, the (n+2)th can be computed by the following relation T(n+2) = (Tn+1)^2 + T(n) In Python, we can solve the Fibonacci sequence in both recursive as well as iterative way, but the iterative way is the best and easiest way to do it.
