A Fibonacci sequence is a series of numbers that starts with a zero, followed by a one, and proceeds based on the rule that each number(called a Fibonacci number) is equal to the sum of the preceding two numbers. 0,1,1,2,3,5,8,13,21,34,… •It starts with 0 & 1. •The next number 1 is found by adding the two numbers before it(1+0). •Similarly, the number 21 is found by adding the two numbers before it(13+8). •And the number 34 from (21+13). •And so on… Here is the list 0,1,1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597, 2584,4181,6765,10946,17711,28657,46368,75025,121393, 196418,317811,.... Step1 :Input the number (n) till which the Fibonacci series will run Step2 :Let assign a variable a equal to -1 and b equal to 1 Step3 :We add variable a & b and assign it to variable x Step4 :Display the value of x Step5: Assign the value of b to va...
