How do you find the rule in a reducing pattern?
For example:
Find the Rule. What are the next 4 steps: 50, 40, 31, 23, 16…..

In this lesson you will learn about determining the rule in
patterns that decrease by using a table.

Let’s ReviewA Common Mistake
When finding the rule in a pattern, don’t assume all patterns increase.
