Question

State true or false.
A.M. of any $n$ positive numbers $a_{1}, a_{2}, a_{3}, . . . ., a_{n}$ is $A$ then $A = \frac{a_{1} + a_{2} + . . . . + a_{n}}{n}$

Solution

The correct option is A True
Arithmetic mean is the average of all the numbers.

Hence for n positive numbers:
$a_{1}$ , $a_{2}$ , $a_{3}$ ,.... $a_{n}$ , the arithmetic mean is $\frac{a_{1} + a_{2} + a_{3} + . . . + a_{n}}{n}$ .
