If lamar follows the pattern below how many tiles will he need for his seventh figure the top one

The pattern here is multiply by 2. Since we can see that the first four numbers are 1, 2, 4, 8, the pattern here is definitely multiply by two. Now, to find the number of tiles he will need in the 7th tile, we will need to raise 2 to the power of something. Since we are multiplying by 2, we are getting different powers of two. The first figure, 1, is two to the power of 0, which means that the power of two for each figure is the figure number minus 1. So, the 7th figure would have tiles which is equal to 64.
