A Correct answer
Explanation

The pattern is n^2 - 1: 0^2-1=-1 (no), 1^2-1=0, 2^2-1=3, 3^2-1=8, 4^2-1=15, 5^2-1=24, 6^2-1=35, 7^2-1=48. The series should be 0, 3, 8, 15, 24, 35, 48. The number 23 is wrong.

AI explanation

The differences between the consecutive terms of the given series are 3, 5, 7, 8, 12, and 13. The logical pattern requires the differences to be consecutive odd numbers starting from 3, which are 3, 5, 7, 9, 11, and 13. Since 8 is present instead of 9, the term 15 + 9 should be 24, making 23 the wrong number. The result is 23.
