C Correct answer
Explanation

The pattern is division: 19200/10 = 1920; 1920/8 = 240; 240/6 = 40; 40/4 = 10; 10/2 = 5.

AI explanation

The series is generated by dividing the previous term by a sequentially decreasing integer. The divisors are 10, 8, 6, and 4, yielding 19200 / 10 = 1920, 1920 / 8 = 240, 240 / 6 = 40, and 40 / 4 = 10. The next divisor is 2, so the final term is 10 / 2, which equals 5.
