For the arithmetic sequence
a₁, a₂, a₃, ...,
The n-th term is

where d = common difference.
Because a₁₀ = 41,
a₁ + 9d = 41 (1)
Because a₁₅ = 61
a₁ + 14d = 61 (2)
Subtract (1) from (2).
5d = 20
d = 4
From (1), obtain
a₁ = 41 - 9*4 = 5
Therefore
a₃ = 5 + 2*4 = 13
Answer: a₃ = 13
First, you need to knw the keywords to the problem. Depreciate means to diminish or become less, therefore, you are taking away something from a number.
You start off with $24,000.
From 100%, you take away 7%
100% - 7% = 93%
Now you put the 93% in decimal form:
93% = 0.93
Add it into your equation:
f(x) = 24,000(0.93)^10
Therefore, your answer is A.
