Question

State true/false:

Arithmetic mean of first five natural numbers is $3$.

• A. True
• B. False

Answer 1

The correct option is A True

First five natural numbers are $1,2,3,4,5$

arithmetic mean = $\frac{\text{sum of terms}}{\text{total number of terms}}$

$=\frac{1+2+3+4+5}{5}$

$=\frac{15}{5}=3$

Arithmetic mean of first five natural number is $3$.

Hence the given statement is true.
