Accepted Answer

i By arranging the numbers in ascending order We get 2 2 3 5 7 9 9 10 11 We know that n 9 is odd So we get Median n 1 th term By substituting the values Median 9 1 th term It can be written as Median value of the 5th term 7 We get Median 7 ii By arranging the numbers in ascending order We get 6 8 9 15 16 18 21 22 25 We know that n 9 is odd So we get Median n 1 th term By substituting the values Median 9 1 th term It can be written as Median value of the 5th term 16 We get Median 16 iii By arranging the numbers in ascending order We get 6 8 9 13 15 16 18 20 21 22 25 We know that n 11 is odd So we get Median n 1 th term By substituting the values Median 11 1 th term It can be written as Median value of the 6th term 16 We get Median 16 iv By arranging the numbers in ascending order We get 0 1 2 2 3 4 4 5 5 7 8 9 10 We know that n 13 is odd So we get Median n 1 th term By substituting the values Median 13 1 th term It can be written as Median value of the 7th term 4 We get Median 4
