The series of even numbers is ; 2, 4, 6, 8,..........number of terms = 2n. i.e. number of terms are even since 2n/2 = n mid term is n th term and (n+1) th term therefore n th term of the above series = 2n and (n+1)th term of the series = 2(n+1) therefore median is the average of the nth term and (n+1)th term median=2n +2(n+1)/2=n +( n+1)=2n+1
