**Handshake Problem** is a classic word problem that can be solved using a table of values.

Read the instructions and make a table with “People” in the left-hand column and “Handshakes” in the right-hand column. Use the visual to assist you. Write the pattern rule that will allow you to predict the number of handshakes when there are *n* people**.**
