A tile pattern has 10 tiles in Figure 2 and increases by 2 tiles for each figure. Find a rule for this pattern and then determine how many tiles are in Figure 100. Homework Help ✎
Work backwards from Figure 2 to find out the starting number of tiles.
Consider using a table, illustration, or graph to help you solve.
y = mx + b
m = growth rate
b = starting number of tiles
To find how many tiles are in figure 100, substitute 100 for x and solve for y.
