Ok so since each pie requires 3 cups of sugar, you would just multiply the x value by 3. For example for one pie three cups of sugar are needed, for two pies six cups of sugar are needed, for three pies nine cups of sugar are needed etc. Hopefully this helps!
5 - 1 = 4 = 2^2
14 - 5 = 9 = 3^2
30 - 14 = 16 = 4^2
55 - 30 = 25 = 5^2
Start with 1, then add 2^2, 3^3, 4^2, 5^2, 6^2, etc.
