Remember that f 0 = 0, f 1 = 1, f 2 = 1, f 3 = 2, f 4 = 3, f 5 = 5, …. Given a number positive number n, find value of f 0 + f 1 + f 2 + …. Fibonacci Sequence. For example, 21/13 = 1.615 while 55/34 = 1.618. The Fibonacci sequence has been studied extensively and generalized in many ways, for example, by starting with other numbers than 0 and 1, by adding more than two numbers to generate the next number, or by adding objects other than numbers. It can be written like this: Which says that term "−n" is equal to (−1)n+1 times term "n", and the value (−1)n+1 neatly makes the correct +1, −1, +1, −1, ... pattern. If you begin with a different number, you are not finding the proper pattern of the Fibonacci sequence. The Fibonacci sequence is a series of numbers where a number is found by adding up the two numbers before it. The Fibonacci sequence is a pattern of numbers generated by summing the previous two numbers in the sequence. Fibonacci was an Italian mathematician who came up with the Fibonacci numbers. Fibonacci series starts from two numbers − F0 & F1. The Fibonacci series is nothing but a sequence of numbers in the following order: The numbers in this series are going to starts with 0 and 1.
