From the recursive rule, you can tell the initial value is 3 and the common ratio is 12. The explicit rule is always
.. (n-th term) = (initial value)*(common ratio)^(n -1)
Subsituting the values you know, you have
.. an = 3*12^(n-1)

Answer:
3. 3 : 5; 3: 5
Step-by-step explanation:
First, let's find the leght of the sides of each octagon.

The area of an octagon is defined by

Replacing the area

Therefore, the side of the first octagon is 1.6 inches long.
Its perimeter is: 


Therefore, the side of the second octagon is 3.8 inches long.
Its perimeter is
.
Now, let's divide to find each ratio:
(the ratio between sides).
(the ratio between perimeters).
Therefore, the closest ratio is 3. 3 : 5; 3: 5
