D Correct answer
Explanation

The sequence follows a pattern of multiplying by 1.5: 3 * 1.5 = 4.5; 4.5 * 1.5 = 6.75; 6.75 * 1.5 = 10.125; 10.125 * 1.5 = 15.1875.

AI explanation

The series follows a pattern where each term is multiplied by 1.5, and then the multiplier increases by 0.25 each time. Multiplying 4.5 by 1.5 gives 6.75, and multiplying 6.75 by 1.5 gives 10.125. This also perfectly continues with 10.125 multiplied by 1.5 equaling 15.1875. Therefore, the missing term is 6.75.
