The pattern below changes by adding two tiles for each new figure. Use Figure 5 to answer the following questions.

tile | tile | tile | tile | tile | tile | tile | |||||

tile | tile | tile | tile | tile | tile | tile |

Figure 5

How many tiles should be in Figure 7? How do you know?

How many tiles are in figure 5? If you add two tiles for Figure 6 and two more for Figure 7, how many tiles should be in Figure 7?

What could Figure 3 look like? Sketch one possibility.

If there are

tiles in Figure 5, and you take away two for Figure 4 and two more for Figure 3, how many tiles should be in Figure 3? Could there be a Figure 0? If so, how many tiles would it have?

Yes! If you have

tiles and take two away five times, how many tiles should Figure 0 have? If the pattern continues, will there be a figure with exactly

tiles? **Explain**your answer with a sentence*or*a drawing.If Figure 0 has

tiles, how many times do you need to add two tiles to get to tiles?
