Find the mean of first 10 even natural numbers.

Given:

First 10 even natural numbers.

To do:

We have to find the mean of first 10 even natural numbers.

Solution:

We know that,

Mean $=\frac{Sum\ of\ the\ observations}{Number\ of\ observations}$

First 10 even natural numbers are 2, 4, 6, 8, 10, 12, 14, 16, 18 and 20.

Therefore,

The mean of first 10 even natural numbers $=\frac{2+4+6+8+10+12+14+16+18+20}{10}$

$=\frac{110}{10}$

$=11$

Hence, the mean of the first 10 even natural numbers is $11$.
