Find the wrong number in the series: 110, 130, 143, 159, 184, 215, 258.

Correct answer: 184

Solution

The differences are 20, 13, 16, 25, 31, 43, which do not follow a consistent pattern. If we inspect the intended progression, 159 to 184 is likely the error because the series should maintain a smoother incremental pattern. Thus, 184 is the wrong number.
