<h3>2, 6, 10</h3>

Step-by-step explanation:

Tom = s

Nancy = r

s=r-2 = Tom=Nancy-2

This means that Tom has $2 less than Nancy as they stayed in the information they gave us. They want us to complete the graph.

Since Tom has $2 less than Nancy all we have to do is apply rule -2 to each number.

4-2=2

8-2=6

12-2=10

Therefore the numbers to add to the graph are 2, 6, and 10.
