Question

Find the median of first 20 odd numbers.​

Answer 1

Answer:

Step-by-step explanation:

1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39

Total number=20

MEDIAN=(n+1)/2 term

N=20

so,Im

(20+1)/2

21/2

=10.5 term

Approx=11 term

MEDIAN=21

Answer 2

Answer:

Step-by-step explanation:

If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

Since two consecutive odd numbers differ by two, the first 20 odd natural numbers are ... Hence, Mean = Sum of the 20 odd natural numbers/total number of numbers = 400/20 .... To find the last term, we need to know the term of the sequence.
