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?

as in your series of numbers i; 1,2,3,4,5,6,7?

no. The series I'm told to find a recurrence relation for has the first 7 numbers given to me. I know have to find a recurrence relation for these numbers.
