Peggy has been studying a type of bacteria that triples every month. originally, there were 2 bacterial cells. she wants to know how many there will be after 24 months. which equation should she use?

Let  represent the number of bacteria after n months.

is the original number of bacteria







so it is clear that :



After 24 months, there will be many bacteria.

 

the equation:
, where u_n is the number of bacteria after n months,

There should only be 1 solution
