# Week 2 – Geometric Sequences

This week I learned about geometric sequences.

Here is a common question:

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 input all the values you have into the formula $t_{n}=ar^{(n-1)}$. Using BEDMAS go step by step to find your answer.
