Examine the pattern of tiles at right. Homework Help ✎ On graph paper, draw Figures 4 and 5.

What would Figure 10 look like? How many tiles would it have on each side? What about Figure 100?

Cami has a different pattern. She decided to represent the number of tiles in her pattern in a table, as shown below. Can you use the table to predict how many tiles would be in Figure 5 of her tile pattern? How many tiles would Figure 8 have? Explain how you know.

Figure 1 is a 2-by-2 square.

Figure 2 is a 3-by-3 square.

Figure 3 is a 4-by-4 square.

That means Figure *x* should be a (*x* + 1)-by-(*x* + 1) square.

Refer to part (a).

Figure 10: An 11-by-11 square that would have 121 tiles.

Can you use the pattern to find what Figure 100 would look like?

Find the pattern in the chart.
