You can put this solution on YOUR website! A culture of bacteria has 20 cells in it. The number of cells doubles every 30 minutes
-------------
A) write the first 5 terms of this sequence
Using 30 mins as the period:
20, 40, 80, 160, 320
------------------
B)is this sequence arithmetic or geometric? Explain how you know
Geometric. The terms are multiplied, not added to.
------------------------
C)write the general term for the sequence
C = 20*2^n where C = # of cells, n = # of periods
--------------
D)use your formula to determine the number of cells after 8 hours
8 hours = 16 periods
C = 20*2^16
C = 1310720 cells
