Final answer:
To find the wrong term in the number series, observe the pattern of alternating addition and subtraction. The wrong term is 23.
Step-by-step explanation:
To find the wrong term in the number series, we need to observe the pattern and identify any inconsistencies. Looking at the series: 3, 2, 8, 12, 13, 24, 18, 32, 23, 42. The pattern seems to be alternating between addition and subtraction of certain numbers. The sequence starts with a subtraction of 1, followed by an addition of 6, then subtraction of 5, and so on.
However, when we reach the term 23, instead of adding or subtracting a consistent number, we have a deviation from the pattern. Therefore, the wrong term in the series is 23.
