Figure 3 of a tile pattern has

Make either an illustration, a graph, or a table and work backward (using the growth rate) to find the starting number of tiles at Figure 0.

Use the starting number of tiles and the growth rate to write a rule where the total number of tiles and

*the figure number.*

Plug in and solve for

*to find the number of tiles that Figure 50 will have.*

Figure 50 will have
