To solve a geometric sequence problem, you can follow these easy steps:

1. Find the first term ($a$): This is the number where the sequence starts.

2. Figure out the common ratio ($r$): You can find this by dividing the second term by the first term.

   So, $r = \frac{a_2}{a_1}$.

3. Use the nth term formula: The nth term ($a_n$) can be found using this formula:

   $a_n = a \cdot r^{(n-1)}$.

4. Find specific terms: Plug in the values you have to get any term in the sequence you want.

5. Check your answers: Make sure your results match what you found in the previous steps.

That's it! By following these steps, you can easily work through a geometric sequence problem.
