Question

The table below illustrates the growth rate of bacteria spores in a laboratory ?

Answer 1

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;

$a_x=2^n$

At n=1;

$a_x=2^1=2$

and others follow the formular.

At n=2,3, and 4
