The beginning of the sequence is thus: Even though Fibonacci sequence is very simple, it would be nice to have a some sort of refresher. The series starts with 0 and 1. In the below program everything is similar to that of what we have used in the above program. We must display a Fibonacci series up to that number. In Loop, we are using while loop and counter for generating Fibonacci Series. In the while loop, we are adding two numbers and swapping numbers. Inside the while loop, we first print the first two terms n1 and n2 respectively. It is doing the sum of two preceding items to produce the new one. Two consecutive numbers in this series are in a ' Golden Ratio '. There is a swapping operation in the next line to continue the while loop until the last element of the sequence gets printed. I then need to plot this on a polar graph with the element number as the angle and value of the element in the sequence for the radius 3 Comments . If the condition is true then it will execute the code inside the block of While loop. If the number of terms is more than 2, we use a while loop to find the next term in the sequence. And a second function to cycle through all the numbers we’ve generated. There are various methods to calculate the nth Fibonacci number: 1. like using matrix method or 2. using the golden ratio. We also need to increment the counter in each recursion call and to compare it with the length and continue the loop until it exceeds the length parameter. First the computer reads the value of number of terms for the Fibonacci series from the user. As a slightly better alternative, we could use a while loop, and generate the sequence in the while loop, but end the loop if we reach a number with a length of 1000.
