8 12 16 20. b)

Answer 2

the ist 10 odd numbers are -

1,3,5,7,9,11,13,15,17,19

the total number of elements = 10(even)

medium = [(n/2)th + (n/2 + 1)th ]/2

= [(10/2)th term + (10/2 + 1)th term]/2

=[ 5th + (5+1)th]/2

=[5th + 6th]/2

=(9 + 11)/2

= 20/2

= 10

2) the ist 7 multiples of 4 are -

4,8,12,16,20,24,28

total number of elements = 7(odd)

median = (n+1)/2 th term

= 8/2 th

= 4th term

= 16
