Id P is point lying on the passing through the point $\mathrm{A}(\overline{ \mathrm{i}}-\overline{\mathrm{j}}+3 \overline{\mathrm{k}})$ and parallel to the vector $2\overline{ \mathrm{i}}+\overline{\mathrm{j}}-2\overline{\mathrm{k}}$ such that $\left|\overline{\mathrm{AP}}\right| = 18$ then a position vector of P is
