According to the question,
First six odd numbers which are divisible by ‘7’
7, 21, 35, 49, 63, 77
difference in each value is 14
$\begin{array}{l}\text{ Sn }=\frac{n}{2}[2a+(n-1)d]\\
\text{ Sn }=\frac{6}{2}[2\times7+(6-1)\times14]\\
\text{ Sn }=3(14+70)\\
\text{ Sn }=252\\
\therefore\text{ Average }=\Large\frac{252}{6}\\
=42\end{array}$
