Using the Lucas Number and Lucas Series Calculator. Fibonacci is commonly used to show the pitfalls of a simple recursive solution and to introduce memoization as a concept - the only real issue with recursive solutions in C# is that the compiler doesn't support tail call optimization in places that it could, but the common recursive Fibonacci solution isn't tail recursive anyhow. The first elements of the Fibonacci sequence are the numbers F = 0, F = 1 (or sometimes F = 1, F = 1) and in this tool, you can choose from which number to start generating the series. For example, F-5 = F5 * (-1)^5+1 = F5 * (-1) = -5.
