Step-by-step explanation:
First 20 even numbers in ascending order are:-
2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40.
Total number of terms (N) = 20 (which is even )
Median = [N/2 th term +(N/2 +1) th term ] /2 .
= [20/2 th term + (20/2 +1)th term ] /2.
= [ 10 th term + 11 th term ] / 2.
= (20 +22 )/2
= 42/2
=21 , Answer.
