Let's create a table with column 1 for number of period,
column 2 for Time(minute),
column 3 for Bacteria spores.
It is observed that the bacteria spore is increasing exponentially at each period interval
Let x equals the number of minutes the bacteria have been growing, and
n equals number of period. Then;
At n=1;
and others follow the formular.
At n=2,3, and 4
