Answer:

Option D, 10.25

Explanation:

The difference between the various number in the sequence is as follows

First number = 10

Second number = 10 + 1.75 = 11.75

Third number = 11.75 - 9.25 = 2.5

Fourth Number = 9.25 + 1.75 = 11

Fifth number = 11 - 2.5 = 8.5

Sixth number = 8.5 + 1.75 = 10.25

Hence, option D is correct
