Answer :
Answer:
[tex]a(n)=8.3^{n-1}[/tex]
Choice D is correct
Step-by-step explanation:
The sequence representing the number of raccoons;
8, 24, 72
is simply but a geometric sequence with first term 8 and common ratio 3.
The formula for the n-th term of a geometric sequence with first term x and common ration r is;
[tex]a(n)=xr^{n-1}[/tex]
In the given case, x = 8 and r = 3
We substitute these values in the above formula;
[tex]a(n)=8.3^{n-1}[/tex]
