Arithmetic, geometric, and recursively defined sequences are all reviewed from Common Core Algebra I in this 6 lesson unit. Series are then introduced, with the help of summation (sigma) notation. The structure of both arithmetic and geometric series are used to find formulas for their sums. Finally, a sophisticated look is taken at how geometric series can be used to determine mortgage payments and balances.
