0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19

n= 20

median= (n/2)+1th term + n/2th term/2

= (20/2)+1th term + 20/2th term /2

=10+1th term + 10 th term/2

= 11th term + 10th term/2

= 10+9/2

= 19/2

=9.5

EXTRA

median for odd number= n/2th term

median for even number= (n/2)+1th term + n/2th term/2
