If n is 1 then median is 45/9 = 5

If n is 10 then median is 54/9 = 6

Your method is perfect if n must equal 1 OR 10, because then the integers are consecutive and median = mean.

But median $$\neq$$ mean if n = 2,3,4,5,6,7,8, or 9
n is an integer between 1 and 10, inclusive.

If n = 2, mean = $$\frac{46}{9}=5.1111$$
If n = 7, mean = $$\frac{51}{9}= 5.67$$

Just an issue with the method (absent a mention of extremes and why they work)
