The average human cell that is capable of dividing has a cell cycle of 20 hours. How many cells there would be in one week if they start with one cell at time zero.
"The cell number doubles with each replication cycle, so after one cycle there would be 2 cells, after 2 cycles there would be 4 cells, etc. To find the number of cells plug in your values in the equation 2^n, where n=the number of cycles (2^4). "
