Answer 2

Answer:

firstly arrange all the series in ascending order

Step-by-step explanation:

like

5,8,11,17,10

11 is the mid no. of this series

so ,11 is the median

20,21,22,25,28,32

22 and 25 are the mid no.of this series

so,add 22 and 25

22+25=47

and divide the answer by 2

47/2=23.5

so, 23.5 is the median
