Pick the odd man out of the folowing number sequence? 123 112 133 112 143

Correct Answer: 122

Explanation:

Here the given series is 123 112 133 112 143


It follows a pattern that,


123


123 - 11 = 112


112 + 21 = 133


133 - 31 = 102 (not 122)


102 + 41 = 143


 


Hence, the odd man in the given number sequence is 122 instead of 102.
