A Correct answer
Explanation

The differences are: 195-175=20, 175-150=25, 150-120=30. The next difference should be 35. 120-35 = 85.

AI explanation

The differences between consecutive terms increase sequentially. The differences are 20 (195 - 175), then 25 (175 - 150), then 30 (150 - 120). Therefore, the next difference must be 35, and subtracting 35 from 120 gives the missing term as 85.
