Answer:

Step-by-step explanation:
- We started at 1
- And it seems that index after index it multiplies by 3
- The formula for the geometric sequence defined implicitly is a(n) =a(1)r^(n-1)

Assuming that the aquarium is rectangular, the formula to work out the volume would be
V = L x H x D
Considering that 1 gallon = 231 inches³
Multiply both by 33.75 to get the total number of inches³ (volume)
231 x 33.75 = 7796.25 inches³
If you also want the depth, read on...
Also, there are 12 inches in one foot
Length = 2 x 12 = 24 inches
Height = 1.5 x 12 = 18 inches
Now we can fill in the information we know
7796.25 = 24 x 18 x D
To work out D, we divide the volume by the values we know
7796.25 / 18 = <span>433.125
433.125 / 24 = </span><span>18.046875 inches
</span>18.046875 / 12 = 1.50390625 feet
To the nearest 2d.p. ≈ 1.5 feet
There are only two steps to solve this problem.
The first step is to multiply the whole number (8) by the numerator (1). 8 times 1 equals 8, so 8 is our new numerator and our fraction should look like: 8/4.
The second step is to simplify it down even further. To do so, you need to figure our what multiples by 4 to get the answer of 8. 4 times what equals 8? The answer should be 2, since 4 times 2 multiples to 8.
The answer is: 2.
