6-60.

Figure 3 of a tile pattern has 11 tiles, while Figure 4 has 13 tiles. The pattern grows at a constant rate. Homework Help ✎

Write an equation to represent this situation.

Which figure number will contain 1015 tiles?

Make a table for the pattern. Use the table to write your equation.

How much does the number of tiles increase as the figure number increases?

*y* = 2*x* + 5

Let *y* = 1015 in the equation. Then solve for *x*.
