Question

Find the mean of the first twelve natural numbers.

Answer 1

Calculate the mean of the first twelve natural numbers

Positive numbers, which can be expressed without fractions, are known as natural numbers.

The first twelve natural numbers are $1,2,3,4,5,6,7,8,9,10,11$ and $12$.

The sum of the first twelve natural numbers $\sum x=1+2+3+4+5+6+7+8+9+10+11+12=78$.

The total number of terms, $n=12$.

The mean of the given data can be found by, $\overline{x}=\frac{\sum x}{n}$.

Thus, the mean of the first twelve natural numbers $\overline{x}=\frac{\sum x}{n}=\frac{78}{12}=6.5$.

Therefore, the mean of the first twelve natural numbers is $6.5$.
