### Re: How do I solve this Recurrence Relation

thank you very much :D . It is exactly what I was looking for.

### How do I solve this Recurrence Relation

I discovered this function in the course of my explorations and I do not know how to take the recursion out of it so I can make it continuous F(0)=0 F(x)=F(x-1)*(n-2) + n^(x-1) if I take an n sided die and roll it x times it tells me the number of results (out of n^X total) that have an odd number o...

The reason mathematical constants are small is because they are numbers someone found interesting, and to be an interesting number you have to be small enough to be held in someone's head.
