Sum of a Special Number Series

# Introduction

In this project, you will learn how to calculate the sum of the first N (N >= 6) terms of a special number series. This series is defined by the following pattern:

$\frac{2}{1} + \frac{3}{2} + \frac{5}{3} + \frac{8}{5} + \frac{13}{8} + \frac{21}{13} + ...$

The numerators of this series are the Fibonacci numbers (2, 3, 5, 8, 13, 21, ...), and the denominators are also the Fibonacci numbers (1, 2, 3, 5, 8, 13, ...).
