A certain organism begins as three cells. Each cell splits and becomes two cells at the end of two days. At the end of another two days, every cell of the organism splits and becomes two cells. This process lasts for a total of 8 days, and no cells die during this time. How many cells are there at the end of the 8th day?
So, on the 0th day, there are 3 cells.
On the 2nd day, there are 6 cells.
On the 4th day, there are 12 cells.
On the 6th day, there are 24 cells.
On the 8th day, there are 48 cells :D
