Explanation

The series is a sequence of squares: 12^2, 11^2, 10^2, 9^2, 8^2, 7^2, 6^2, 5^2. The terms should be 144, 121, 100, 81, 64, 49, 36, 25. 35 is the wrong term.

AI explanation

The series follows the pattern of decreasing perfect squares: 144, 121, 100, 81, 64, 49, 36, 25. The square of 6 is 36, but the series incorrectly lists 35 in its place. Therefore, 35 is the wrong term.
