Найдите длину вектора $\overrightarrow{n}=2\overrightarrow{a}-3\overrightarrow{b}$ ,если $\overrightarrow{a}\left\{1;\ -1;\ 2\right\}\ и\ \overrightarrow{b}\left\{2;\ 2;\ 0\right\}$

Если $\overrightarrow{a}\left\{-2;\ 1;\ 3\right\},\ \overrightarrow{b}\left\{6;\ 2;\ 0\right\}$ , то вектор $\overrightarrow{a}+\overrightarrow{b}$ имеет координаты

Точка M - середина отрезка AC.
$M\left(2;\ 1;\ 1\right),\ A\left(3;\ -2;\ 4\right)$ .
Найдите координаты точки C.
