Question

Find the mean of :

First $6$ multiples of $7$

Answer 1

Step 1: Listing the first $6$ multiples of $7$

First $6$ multiples of $7$ are $7,14,21,28,35,42$

Step 2: Finding the mean of first $6$ multiples of $7$

$\begin{array}{rcl}Mean& =& \frac{sumofallvalues}{Numberofvalues}\\ & =& \frac{7+14+21+28+35+42}{6}\\ & =& \frac{147}{6}\\ & =& 24.5\end{array}$

Hence, the mean of first $6$ multiples of $7$ is $24.5$
