Find a Recurrence Relation: Step-by-Step Guide

AI Thread Summary
To find a recurrence relation from a series of numbers, one must identify patterns within the given data. Simply having the first seven numbers is not sufficient; understanding the problem's context is crucial. Participants suggest posting specific questions in homework forums to facilitate clearer discussions. Spotting numerical patterns is essential for deriving the relation. Engaging with the community can provide valuable insights and guidance.

How do you find a recurrence relation from a given problem?
 
Mathematics news on Phys.org
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.

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!
