Answer 6

\(\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ a}}\quad ,&{\color{blue}{ b}})\quad &({\color{red}{ c}}\quad ,&{\color{blue}{ d}})
\end{array}\qquad
\left(\cfrac{{\color{red}{ x_2}} + {\color{red}{ x_1}}}{2}\quad ,\quad \cfrac{{\color{blue}{ y_2}} + {\color{blue}{ y_1}}}{2} \right)\\ \quad \\ \quad \\



\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ 25}}\quad ,&{\color{blue}{ 5}})\quad &({\color{red}{ a}}\quad ,&{\color{blue}{ b}})
\end{array}\qquad
\left(\cfrac{{\color{red}{ a}} + {\color{red}{ 25}}}{2}\quad ,\quad \cfrac{{\color{blue}{ b}} + {\color{blue}{ 5}}}{2} \right)\implies (18\ ,\ -1)\\ \quad \\

\cfrac{{\color{red}{ a}} + {\color{red}{ 25}}}{2}=18\qquad \qquad
\cfrac{{\color{blue}{ b}} + {\color{blue}{ 5}}}{2}=-1\)
