Answer:

C

Step-by-step explanation:

There is a common ratio between consecutive terms

r = 24 ÷ 16 = 36 ÷ 24 = 54 ÷ 36 = 1.5 = \frac{3}{2}

This indicates the sequence is geometric with nth term ( explicit formula )

f(n) = a₁(r)^{n-1}

where a₁ is the first term and r the common ratio

Here a₁ = 16 and r = \frac{3}{2} , then

f(n) = 16 (\frac{3}{2}) ^{n-1} → C

4.1x = 270.6

Divide 4.1 to both sides:

x = 66
