4-75.

Figure 3 of a tile pattern has tiles, while Figure 4 has tiles. If the tile pattern grows at a constant rate, how many tiles will Figure 50 have? Homework Help ✎

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 for and solve for to find the number of tiles that Figure 50 will have.

Figure 50 will have tiles.
