To solve this logical series, let's analyze the pattern between each term.
From the given series: 2, 6, 12, 36, 72, __
We can observe that each term is obtained by multiplying the previous term by a constant factor.
2 * 3 = 6
6 * 2 = 12
12 * 3 = 36
36 * 2 = 72
Therefore, the next term can be found by multiplying 72 by 3:
72 * 3 = 216
Hence, the missing term in the series is 216.
So, the correct answer is option B) 216.
