Question

Find the mean of the first ten natural numbers.

Answer 1

Calculate the mean of the first ten natural numbers

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

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

The sum of the first ten natural numbers, $\sum x=1+2+3+4+5+6+7+8+9+10=55$.

The total number of terms, $n=10$.

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

Thus, the mean of the first ten natural numbers $\overline{x}=\frac{\sum x}{n}=\frac{55}{10}=5.5$.

Therefore, the mean of the first ten natural numbers is $5.5$.
