In this worksheet, we will learn about using patterns to predict how shapes grow.

*For Example:*

Question: ** ** How many squares are used in Pattern #100?

Answer: ** ** If you double the number of white squares along one arm and add one grey square you will get the total number of squares. Pattern #100 has 100 squares along one arm.

We can use the formula 2 x N +1 where N is the number of squares along one arm or the Pattern number.

This gives us 2 x 100 +1 = 201 squares
