Question

The mean of first ten odd numbers is-

Answer 1

Answer:

10

Step-by-step explanation:

First ten odd natural numbers are

1 ,3 ,5 ,7 ,9 ,11 ,13 ,15 ,17 ,19 

mean = sum of all the observations / Total number of observations

         = 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 / 10

         = 100 / 10

          = 10

 So the mean is 10

Answer 2

$\frac{1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19}{10}$
$\frac{100}{10}$
=10
