58 is the wrong item in the series.
The question is: 15,22,30,39,49,58,72. You've missed 49.
Explanation:
From the starting element of the series, the procedure followed is:
current number + i = next number,
where i value starts from 7 and keeps on increasing by 1 on every succession.
15 + 7 = 22
22 + 8 = 30
30 + 9 = 39
39 + 10 = 49
49 + 11 = 60, but here it is given as 58. So, it is the wrong number
60 + 12 = 72
The series should be 15,22,30,39,49,60,72
Therefore, 58 is the wrong number in the series 15,22,30,39,49,58,72.
