It is the 'rth' term, which represents the general term.

Have you looked at

*any*examples at all that are similar to your question? Perhaps in your class notes or textbook ....?

Before you can be helped any further, you need to show what you got for the general term. If you cannot get the general term, you need to show what you've tried and where you get stuck.
