# Recursive equation to write a sequence

Site Navigation Geometric Sequences This lesson will work with arithmetic sequences, their recursive and explicit formulas and finding terms in a sequence.

Try to figure it out on your own, then come back with the code if you can't do it. I'm not lazy the code is shorter than this comment. I got rid of the map range function and am using only a range startNumber, endNumber function.

Now the problem I have is where to use the while statement.

I try at the beginning of the function but of course there is a billin an done lines of error. Where should I be putting it? Feb 3 '09 at Try then to figure out where your program is wrong. Try to convert the "by-hand method" in code.

This is for exercise, to learn. I could put down two lines of code but I don't think you'll learn anything from them.

Other approaches can handle an n of or more without blowing up or losing precision. But I think this answer demonstrates better usage of the language. You can demonstrate how slow it is by using the following: You can see how much faster it is visually by doing this: As I have been learning Haskell, I came across this implementation in Haskell: Usually,whereas the Haskell version can go up to the s of millions, although it uses all 8 GB of my laptop's memory to do so:For a sequence a 1, a 2, a 3,, a n, a recursive formula is a formula that requires the computation of all previous terms in order to find the value of a n.

Note: Recursion is . C# Helper contains tips, tricks, and example programs for C# programmers. Sep 07,  · How to Solve Recurrence Relations.

In trying to find a formula for some mathematical sequence, a common intermediate step is to find the nth term, not as a function of n, but in terms of earlier terms of the sequence.

Write the generating function of the sequence. The objective in this step is to find an equation that will allow us to 66%(54). There are 80 fish in a Koi pond. Each year the population decreases by 25%. Which explicit formula generates a sequence of fish in the pond each year?
