Answer: B) 32 Explanation: Here the given series follows a pattern that, 22 - 0 = 4 32 - 1 = 8 42 - 2 = 14 52 - 3 = 22 62 - 4 = 32 Hence, the missing number is 32 Method 2 :: The difference between 4 and 8 is 4, the difference between 8 and 14 is 6, the difference between 14 and 22 is 8. So the next difference between 22 and the next number will be 10 since it follows (4,6,8,10 - add +2 each time) Hence, 22 + 10 = 32 is the missing number.
