Correct Answer: 30240


Solution : Given:
6, 12, 36, 144, 720, 4320, ?

Multiply each previous term by consecutive natural numbers starting from 2 to get the next term.
6 × 2 = 12; 12 × 3 = 36; 36 × 4 = 144; 144 × 5 = 720; 720 × 6 = 4320; 4320 × 7 = 30240

So, 30240 is the missing number in the given series. Hence, the second option is correct.
