On Monday a toy store sold 4 race cars. on Tues it sold 8 race cars. on Wed it sold 16 race cars. suppose this pattern continues. how many race cars will be sold on Fri? describe a rule then solve

You have to multiply each number by the number two, to get the next number in the series. Friday 64 cars will be sold. c = cars the day before the day trying to be solved for, and y = the outcome. c x 2 = y.

Monday 2 x 2 = 4

Tuesday 4 x 2 = 8

Wednesday 8 x 2 = 16

Thursday 16 x 2 = 32

Friday 32 x 2 = 64

They will sell 64 because its doubling it
