Question

find the mean of first ten odd natural numbers

Answer 1

Mean of the 1st  10 odd natural number is 10

To Find:

Mean of 1st 10 odd natural number

solution:

$\text{Mean} =\frac{\text { Sum of the terms }}{\text { Number of terms }}=\frac{1+3+5+7+9+11+13+15+17+19}{10}\\ \\ \text{Mean} =\frac{100}{10}=10$

Natural numbers are positive integers from 1, 2 … infinity

Odd numbers starts from 1, 3, 5 … infinity

The first 10 odd natural numbers are 1, 3, 5, 7, 9, 11, 13, 15, 17, 19

The mean of the first 10 odd natural number is 10

Answer 2

Answer:

$Mean \:of \:first \:10\:odd\\natural \: numbers = 10$

Step-by-step explanation:

/* Sum of first 'n' odd natural numbers = n² */

Sum of first ten odd natural numbers = 10² = 100

$Mean = \frac{sum \:of \: first \:10\:odd\: numbers }{10}$

$=\frac{100}{10}\\=10$

Therefore,

$Mean \:of \:first \:10\:odd\\natural \: numbers = 10$
