Understand Geometric Sequence
Applying the rules of geometric sequences to solve real-world problems.
Mapped to CCSS Section# HSA.SSE.B.4, HSF.BF.A.2
Derive the formula for the sum of a finite geometric series (when the common ratio is not 1), and use the formula to solve problems. For example, calculate mortgage payments. Write arithmetic and geometric sequences both recursively and with an explicit formula, use them to model situations, and translate between the two forms.
