Figure 3 of a tile pattern has 11 tiles, while Figure 4 has 13 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 y = the total number of tiles and x = the figure number.
Plug in 50 for x and solve for y to find the number of tiles that Figure 50 will have.
Figure 50 will have 105 tiles.
