Answer 2

The missing number of the given sequence = 10.25

Step-by-step explanation:

The given sequence :

10, 11.75, 9.25, 11, 8.5, ?

To find, the missing number of the given sequence = ?

The pattern follow:

Previous number + 1.75, Previous number - 2.5, Previous number + 1.75, Previous number - 2.5, .......

11.75 = 10 + 1.75 = 11.75

9.25 = 11.75 - 2.5 = 9.25

11 = 9.25 + 1.75 = 11

8.5 = 11 - 2.5 = 8.5

Similarly,

? = 8.5 + 1.75 = 10.25

∴ The missing number of the given sequence = 10.25
