Correct Answer: 21600


Solution : Given:
30, 60, 180, 720, 3600, ?

In the above-given series, multiply the number with consecutive natural numbers starting from 2 to obtain the next number.
30 × 2 = 60, 60 × 3 = 180, 180 × 4 = 720, 720 × 5 = 3600, 3600 × 6 = 21600

So, 21600 is the missing number of the series. Hence, the second option is correct.
