Question

1) Find the mean and median of first 9 even numbers.​

Answer 1

Answer:

mean=10

median=10

Step-by-step explanation:

First 9 even no= 2,4,6,8,10,12,14,16,18

mean= sum of terms/no of terms

= 2+4+6+8+10+12+14+16+18/9

=90/9

=10

Median= n+1/2

= (9+1)/2

= 10/2

= 5th no

=2,4,6,8,10,12,14,16,18

=10

Answer 2

median is 8

and mean is

An even number is the number put in the form 2n

And an odd number is of the form 2n+1

Where n starts from 0. So since you can’t put 9 in the form of 2n, it is an odd number.

9= 2n+1 = 2(4)+1

Here n=4

So 9 is odd!!!
