Huh?

I think you need to give us some more info: what is the problem you are thinking of?

There is no "formula". You have to understand the definitions, understand what the problem is telling you and then think!

I've got a series of numbers starting with n=1 going up to n=7. I am told there exists a recurrence relation. Is that enough data to find this relationship?

What you will need to do is to spot a pattern with the numbers. You should post your specific question in the homework forums, and show us what you have done towards answering the problem. Such a cryptic conversation as this will not help anyone!
