## Week 2 in Precalc 11

Tell:

This week I have learned how to determine a certain value for different geometric sequences, by using specific formulas created to find those results.

Show:

Explain:

In solving this problem you first need to find “R” by using the formula $\frac{t_2}{t_1}$. Once you have found “R”, you can determine $t_1$ by looking at the terms left to right. With all the information you have found now you can plug it all into the formula $t_n = t_1 * R ^(n-1)$. Using BEDMAS go step by step to find your answer.
