Submitted by Abhishek Pathak, on October 22, 2017 The fibonacci series is one of the famous series that is also asked in many interviews as a coding question. fib(n)=fib(n-1)+fib(n-2), edit So, to get the nth Fibonacci term we can follow Given a number N return the index value of the Fibonacci sequence, where the sequence is: After a quick look, you can easily notice that the pattern of the sequence is that each value is the sum of the 2 previous values, that means that for N=5 → 2+3 or in maths: If found positive, it will terminate the execution and will give the list else it will sustain on execution. The first two numbers of Fibonacci series are 0 and 1. Later we have initialized the variable var1 and var 2 that store the values 0 and 1, respectively, as these are the two mandatory values in the Fibonacci series that kicks the process required to develop the series. … var sum = fseries(var1 - 1); Please Improve this article if you find anything incorrect by clicking on the "Improve Article" button below.
