Answer:
Bacteria population In generation n
pₙ = 120 (3ⁿ⁻¹)
Explanation:
The pattern that the bacteria Population follws a geometric series' pattern with the first term equal to the population in the first generation, 120 bacteria, the population in the second generation is the second term and so on.
First term = a = population in the first generation = 120
Second term = a₂ = population in the second generation = 360
Third term = a₃ = population in the third generation = 1080
The general formula for any term of a geometric series is
aₙ = arⁿ⁻¹
a = first term
r = common ratio
But for a geometric series, common ratio is given as the next term divided by the very previous term.
r = (aₙ/aₙ₋₁)
For this question,
r = (360/120) = (1080/360) = 3
So, the right model for the profits for any given year n is
pₙ = 120 × 3ⁿ⁻¹
pₙ = 120 (3ⁿ⁻¹)

The Tropic of Capricorn (or the Southern Tropic) is the circle of latitude that contains the subsolar point on the December (or southern) solstice. It is thus the southernmost latitude where the Sun can be directly overhead. Its northern equivalent is the Tropic of Cancer.
