Answer:

Himanshi Verma

 We know, 

if the number of observation (n) is even 

then, 

1. first of all find the value at the position 

2. and find the value at the position 

3. now find the average of two value to get the median .

e.g., 


Given, 11, 12, 14, 18, (x + 2), (x + 4) , 30, 32 , 35 , 41 are in ascending order .

number of terms = 10 {even} 


so, median = {(n/2)th + (n/2 + 1) th }/2 

24 = (5th + 6th)/2 

24 = {(x + 2) + (x + 4)}/2 

24 = (x + 3) 

x = 21 


hence, x = 21
