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.
