D Correct answer
Explanation

The terms represent a number followed by its square: 2, 4; 4, 16; 6, 36; and 8, 64. The next pair should be 10, 100, so 981 is the incorrect term.

AI explanation

The logic of the series is to add the square of consecutive odd numbers to the previous term. The first term is 24; adding 1 squared gives 25, which does not fit. Alternatively, adding consecutive cubes gives 24, and 4 cubed is 64, but 24 + 64 is 88 instead of 416. Following the correct option, we multiply the term by a number and add a value, but since 981 does not fit the multiplication pattern of the others, it is the wrong term. The wrong term is 981.
