Try It Out -- Chapter 4, Lesson 4: Solve Problems Using a Table of Values

Kenojuak is building an igloo with her family. She wants to stack blocks of snow in a circular arrangement with 10 rows. There is one block at the top, and 4 blocks in the 2nd row, 7 blocks in the 3rd row, and so on. Kenojuak needs to know the number of blocks of snow to carve for the whole igloo. Order the steps she takes to solve the problem.

She calculates the total number of blocks and checks her calculations by extending the table of values.
She notices a pattern. When she adds the number of blocks in the 1st row to the number of blocks in the 10th row, she gets a total of 29 blocks. The same thing happens when she adds the number of blocks in the 2nd row and the 9th row.
She knows that each row has 3 more blocks than the row above. She needs to find out how many blocks are in 10 rows.
She decides to make a table of values and look for a number pattern.
