Time in hours, At time 0, there is 1 bacterium At time 1, there are 2 bacteria At time 2, there are 2*2 = 2^2 bacteria At time 3, there are 2^3 bacteria etc.
Must I continue this pattern and stop at 20?
yes. actually its just one step. at time 20,there will be 2^20 bacteria. (2^x where x is the amt of time)
I got it now. Thanks!
