Figure 3

Represent the number of tiles in each figure in an

table. Letbe the figure number andbe the total number of tiles.Use the table to graph the pattern.

How do the figures change as the pattern continues?

Look at your table from part (a).Without drawing Figure 5, predict where its point would lie on the graph. Justify your prediction.

Is there a trend in the way your points lie on the graph?

Use the eTool below to complete parts (a) and (b).
