The position vectors of points P and Q are $\displaystyle \overrightarrow{\mathrm{p}}$ and $\displaystyle \overrightarrow{\mathrm{q}}$ respectively. The point R divides line segment PQ in the ratio $\displaystyle 3: 1$ and S is the mid-point of line segment PR. The position vector of $\displaystyle S$ is :
