We finished our review of sequences today, and if you missed any part of it you can find the completed notes here. I would also recommend you watch this video to catch up on some of the important parts of what you missed.
Your homework is Topical Review – Sequences (HW). This is a collection of actual Regents questions that have come up about arithmetic and geometric sequences, so it should give you a good idea of what you need to be able to do. Remember that this homework assignment is worth two credits!
