C Correct answer
Explanation

The pattern is: (number÷2)-n, where n decreases by 20 each time. 9880÷2-20=4920, 4920÷2-40=2420, 2420÷2-60=1150, 1150÷2-80=495, 495÷2-100=147.5. The missing term is 1150, matching option C. This involves halving each term and subtracting a progressively larger amount (20, 40, 60, 80, 100).
