D Correct answer
Explanation

The sequence consists of multiples of 11: 3*11=33, 8*11=88, 11*11=121, 17*11=187, 26*11=286, 31*11=341. The term 287 is incorrect; it should be 286.

AI explanation

The sequence follows a pattern of adding 55, then subtracting 33, and repeating this alternating addition and subtraction. The term 187 plus 55 gives 242, which means the next term should be 242 instead of 287. Therefore, 287 is the wrong term in the sequence.
