Question
Find the mean of:
The first ten odd numbers.
The first ten odd numbers.
✓
Answer
First ten odd numbers are:
1, 3, 5, 7, 9, 11, 13, 15, 17 and 19
$\therefore\ \text{Mean}=\frac{\text{Sum of number}}{\text{Total numbers}}$
$=\frac{(1+3+5+7+9+11+13+15+17+19)}{10}$
$=\frac{100}{10}$
$=10$
$\therefore\ \text{Mean}=10$
1, 3, 5, 7, 9, 11, 13, 15, 17 and 19
$\therefore\ \text{Mean}=\frac{\text{Sum of number}}{\text{Total numbers}}$
$=\frac{(1+3+5+7+9+11+13+15+17+19)}{10}$
$=\frac{100}{10}$
$=10$
$\therefore\ \text{Mean}=10$
