Find the position vector of the mid point of the vector joining the points P(2, 3, 4) and`Q(4, 1, 2)`.

Explanation

To find the position vector of the midpoint of the vector joining the points P(2, 3, 4) and Q(4, 1, 2), we can follow these steps:

### Step 1: Write the position vectors of points P and Q
The position vector of point P, denoted as **OP**, can be expressed as:
\[ \mathbf{OP} = 2\mathbf{i} + 3\mathbf{j} + 4\mathbf{k} \]
The position vector of point Q, denoted as **OQ**, can be expressed as:
