1-15) a. Finding and using a pattern is an important problem-solving skill you will use in algebra. The patterns in Diamond Problems will be used later in the course to solve other types of algebraic problems.

Look for a pattern in the first three diamonds below. For the fourth diamond, explain how you could find the missing numbers (?) if you know the two numbers (#).

• You add the two numbers on the left and right (#) to get the top number, and multiply them to get the bottom.

• You add the two numbers on the left and right (#) to get the bottom number, and multiply them to get the top.

• You add the two numbers on the left and right (#) to get the bottom number and then add 3 to that sum.
