Correct Answer: 21


Solution : Given:
63, 56, 49, 42, 35, 28, ?

In the above-given series, subtract 7 from the previous number to get the next number.
63 – 7 = 56; 56 – 7 = 49; 49 – 7 = 42; 42 – 7 = 35; 35 – 7 = 28; 28 – 7 = 21

So, 21 is the missing number of the series. Hence, the second option is correct.
