What is a median in a set of numbers?

If its a odd set of numbers then the median will be (n+1/2)th term.

where,

n=set of numbers like

2,4,5 then the median will be (3+1/2)th term=2nd term=4.

therefore the median is 4

And if its a even set of numbers like

1,4,7,9,6,8 then the median will be the (sum of mid numbers/2)

7+9/2=8

therefore the median is 8
