Arrange the sequence in the asending order & in that sequence middle number is the Median of the sequence.

So in your question :

arrange in asending order :
2,3,4,5,6,7,8,9 & n is the other number.

If n is in range of 1 to 5 Than Median is 5
If n is in range of 6 to 10 Than Median is 6

So ans shold be B)

B

For median, arrange all the numbers in ascending order.

Count the numbers. If :
Even = Avg of the middle 2 number
Odd = Middle number

2,3,4,5,6,7,8,9,n......(1)
n,2,3,4,5,6,7,8,9......(2)
(since its mentioned the numbers between 1 and 10, inclusive)

So, we get n = 6 (from 1, since there are only 9 numbers) and n = 5 (from 2, since there are only 9 numbers).

Keep in mind all the numbers are integers, therefore n cannot be a decimal.

Hope this helps.
