Correct Answer: 12


Solution : Given:
56, 42, 30, 20, ?, 6

Subtract consecutive even numbers in decreasing order starting from 14 to get the next number in the series.
56 – 14 = 42, 42 – 12 = 30, 30 – 10 = 20, 20 – 8 = 12, 12 – 6 = 6

So, the required missing number is 12. Hence the second option is correct.
