The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).
BaLLatris [955]

Answer:

a₆ ≈ 25.284

Step-by-step explanation:

There is a common ratio between consecutive terms , that is

8 ÷ 6 = \frac{32}{3} ÷ 8 = \frac{4}{3}

This indicates the sequence is geometric with nth term

a_{n} = a₁ r^{n-1}

where a₁ is the first term and r the common ratio

Here a₁ = 6 and r = \frac{4}{3} , then

a₆ = 6 × (\frac{4}{3}) ^{5} = 6 × \frac{1024}{243} = \frac{6(1024)}{243} ≈ 25.284 ( to the nearest thousandth )
