Find the odd man out of the following number sequence? 3, 5, 13, 43, 167

Correct Answer: 167

Explanation:

The given number series is 3, 5, 13, 43, 167


3


3 x 1 + 2 = 5


5 x 2 + 3 = 13


13 x 3 + 4 = 43


43 x 4 + 5 = 177 (not equal to 167)


 


Hence, the odd number in the given number sequence is 167.
