Answer: Option C


a_n=3(6)^(n-1)

Explanation:

The number of rabbits in each generation can be modeled using a geometric sequence of the form:


a_n=a_1(r)^(n-1)

Where
a_1 is the first term of the sequence,
a_n is the ninth term of the series, r is the common ratio

To find the proportion we divide the consecutive terms of the sequence as shown


(18)/(3)=6\\\\(108)/(18)=6

Then the common ratio is:
r=6

The first term of the series is:
a_1=3

Then the explicit formula is:


a_n=3(6)^(n-1)

The answer is: Option C
