D Correct answer
Explanation

The pattern is: 23*1+1=24, 24*2+2=50, 50*3+3=153, 153*4+4=616. The number 525 is incorrect; it should be 616.

AI explanation

The series follows a pattern of multiplying by an integer and then adding a number that increases by one each time. The calculations are 23 times 1 plus 1 is 24, 24 times 2 plus 2 is 50, and 50 times 3 plus 3 is 153. Following this logic, the next term should be 153 times 4 plus 4, which equals 616. Since the series lists 525 instead of 616, it is the wrong number.
