Correct Answer: 31
Solution :
Given:
104, 108, 54, 58, 29, 31
Add 4 and divide the number by 2 alternatively in each number, to determine the wrong number in the series –
104 + 4 = 108; 108 ÷ 2 = 54; 54 + 4 = 58; 58 ÷ 2 = 29; 29 + 4 = 33 ≠ 31
So, 31 does not belong to the series. Hence, the fourth option is correct.
