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
It's a matter of opinion. In my opinion you can hypothesize all you want, when you get to do it in practice it's almost 100% garantee of failure or incomplete hypothesis. So testing is way more important IMO.
