Arithmetic Sequence Investigation

This arithmetic sequence investigation will support students thinking through the definition of arithmetic sequence, finding equations for arithmetic sequences, finding missing terms, and making the connection to linear functions. Students can work in groups through the investigation until they reach a checkpoint (for class discussion) to think critically and have mathematical discussion about arithmetic sequences. It's amazing how much students can learn through investigation with each other!

This arithmetic sequence investigation can be used as group (2-3 students) discussion, but also full class discussion if needed.

Included in this product is a five-page arithmetic sequence investigation worksheet that includes checkpoints to stop for class discussion as well as a complete answer key. Check out these sequence activities for more practice.
