Question

find the mean and median for the first 15 odd numbers​

Answer 1

Step-by-step explanation:

The first 15 odd numbers are 1,3,5,7,9,1,13,15,17,19,21,23,25,27 and 29

Here n=15, which is odd.

Where, n is the number of the given number.

∴median=valueof1/2(n+1)

th

observation.

=1/2(15+1)

=1/2(16)

=16/2

=8

Then, value of 8

th

term =15

Hence, the median of first 15 odd numbers is 15.

Answer 2

Answer:

1-The first 15 odd numbers are: 1,3,5,7,9,11,13,15,17,19,21,23,25,27,29.

So,

=(15+1)/2 th observation.

=8 th observation.

The median is 15.

2-n= 50 (even)

Median = [(n/2)th term + (n/2 + 1)th term] / 2.

= (24 + 25) /2.
