Explanation

The series is 3, 7, 13, 21, 33, 43, 57. The differences between consecutive terms are 4, 6, 8, 12, 10, 14. While there are multiple potential interpretations of the pattern, 33 is identified as the wrong term in the answer key. This is a number series pattern recognition question where you need to identify which term breaks the underlying sequence.
