In Geometric Sequences, you will learn the common ratio between each term as well as how to find the nth term of a geometric sequence. You will also cover geometric means before retiring to the example questions at the end of the lesson.
You can use the formula for the nth term of a series to find the first term.
If you need to find a particular term and you are given the kth term, first use the kth term to find the first term. Then use the first term to find the term you are asked to find.
When finding geometric means, remember that you might get two different values of r, one positive and the other negative. Use both values to obtain two different sets of geometric means. Each set is a solution to the problem.
