D Correct answer
Explanation

The sequence is 15, x, 240, 960, 3840. Notice 960/240 = 4 and 3840/960 = 4. The multiplier is 4. So 15 * 4 = 60, and 60 * 4 = 240.

AI explanation

Each number in the sequence is multiplied by 4 to obtain the following number, since 240 times 4 is 960 and 960 times 4 is 3840. To find the missing term, divide 240 by 4. This gives the result 60, which is also 15 multiplied by 4.
