In the 1st generation, there are 8 raccoons in a forest.

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;

In the given case, x = 8 and r = 3

We substitute these values in the above formula;

answer: i'm not sure

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
