Give the meaning of each part of the Formula for the Sum of $n$ Terms of a Finite Geometric Series, $S_n=\frac{a_1\left(1-r^n\right)}{1-r}$.

$S_n$ is the $\underline{\quad?\quad}$ of $n$ terms of the series. $n$ is the $\underline{\quad?\quad}$ of terms. $a_1$ is the $\underline{\quad?\quad}$ term. $r$ is the $\underline{\quad?\quad}$.

Now consider what may appear to be a completely different problem: the algebraic expansion of the binomial expression $( a + b ) ^ { n }$ Use what you know about multiplication to complete parts (a) through (d) below. a. Write $( a + b ) ^ { 2 }$ in expanded form . In other words, multiply (a+b)(a+b) and combine like terms. How many terms are there in the resulting polynomial? What are the coefficients of the terms? b. Multiply and rewrite $( a + b ) ^ { 3 }$ in expanded form. How many terms are there, and what are their coefficients? What did you do to expand the polynomial? With your team, discuss possible ways to carry out the polynomial multiplication quickly. c. How many terms do you think $( a + b ) ^ { 4 }$ will have when rewritten in expanded form? Write it in expanded form. What are the coefficients of these terms? d. How could you use Pascal's Triangle to rewrite the binomial expression $( a + b ) ^ { 6}$ as a sum of monomial terms? Explain your method.
