Correct Answer

D

Explanation

It seems like the series you've provided is 3, 2, 4/5, 8/9, 16/27, and so on.To find the pattern or type of this series, let's look at the terms:3, 2, 4/5, 8/9, 16/27, ...It appears that each term is obtained by taking the previous term and either multiplying or dividing it by a certain number. Let's examine the pattern:3 to 2: Divide by 1.52 to 4/5: Multiply by 2/54/5 to 8/9: Multiply by 2/38/9 to 16/27: Multiply by 2/3From this pattern, it seems that each term is obtained by alternately multiplying and dividing by 2/3.So, the type of the series is an alternating multiplication and division series with a common ratio of 2/3.
