B Correct answer
Explanation

This is a geometric progression with a = 2 and r = 3. The nth term is a * r^(n-1). The 8th term is 2 * 3^(8-1) = 2 * 3^7 = 2 * 2187 = 4374.

AI explanation

The series is a geometric progression with the first term 2 and a common ratio of 3. Using the geometric progression formula for the nth term, which is a multiplied by r raised to the power of n minus 1, we get 2 multiplied by 3 to the power of 7. Calculating 2 multiplied by 2187 gives 4374.
