Question
Find the mean of first five multiples of $3$
✓
Answer
First five multiples of $3$ are $3, 6, 9, 12, 15$ $\therefore\text{Mean}=\frac{\text{Sum of numbers}}{\text{Total numbers}}$
$=\frac{3+6+9+12+15}{5}$
$=\frac{45}{5}$
$=9$
$\text{Mean} = 9$
$=\frac{3+6+9+12+15}{5}$
$=\frac{45}{5}$
$=9$
$\text{Mean} = 9$
