My students need practice working the arithmetic and geometric general-term formulas forwards and backwards. The key skill in this worksheet is to give them randomly-selected terms of an arithmetic or geometric sequence, and have them determine the general term for that sequence. I have them check their work as they go.

I use it within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.

The file includes spiral review problems.

This worksheet is intended for students to show their work on a separate sheet of paper.
