Let \( PQR \) be a triangle with \( R(-1, 4, 2) \). Suppose \( M(2, 1, 2) \) is the mid point of \( PQ \). The distance of the centroid of \( \Delta PQR \) from the point of intersection of the lines \( \frac{x-2}{0} = \frac{y}{2} = \frac{z+3}{-1} \) and \( \frac{x-1}{1} = \frac{y+3}{-3} = \frac{z+1}{1} \) is:
