A = 6
tn = a + (n - 1)d
t4 = 6 + 3d = 12
3d = 12 - 6 = 6
d = 6/3 = 2
f(n + 1) = f(n) + 2
The LCD (least common denominator) is the lowest number that both denominators (12 and 5) go into. The lowest number that both 5 and 12 go into is 60. The LCD of the two fractions is 60.

Answer:
24 ft^2
Step-by-step explanation:
The small aquarium:
1 * 3 * 2 = 6 ft^2
The large aquarium
(1 + 1) * (3 + 2) * (2 + 1)
2 * 5 * 3 = 30 ft^2
Difference between the larger aquarium and the smaller aquarium:
30 - 6, or 24.
This means that the answer to this question is a, 24 ft^2
