Work through Geometric Sequences and Exponential Functions to review geometric sequences and the variables and parameters associated with them.


textbook

To review problem solving using geometric sequences, read the example questions on pages 34 and 35 of the textbook.

 

To review arithmetic series, go to page 24 of the textbook and look at the two blue boxes containing formulas that can be used to evaluate the sum of an arithmetic series. See how these formulas are applied in “Example 1” and “Example 2” on pages 25 and 26.

This is a play button that opens Exploring Laws of Exponents.

Use Exploring Laws of Exponents to review the product law of exponents. Select the first box, which represents the product law. You may also want to explore some of the other laws.

Go back to the Are You Ready? section and try the questions again. If you are still having difficulty, contact your teacher.
