Question

Average of the first six even natural numbers is:

• A. $7$
• B. $5$
• C. $3$
• D. $1$

Answer 1

The correct option is A $7$

First six even natural numbers is $2,4,6,8,10,12$.

We know, Mean is given by,

$\text{Mean/Average}=\frac{\text{Sum of the elements}}{\text{Total number of elements}}$.

Here, the number of observations $=6$.

$⟹\text{Mean/Average}=\frac{2+4+6+8+10+12}{6}=\frac{42}{6}=7$.

Therefore, option $A$ is correct.
