To find the values of \(a\), \(b\), and \(c\) such that the origin is the centroid of the triangle with vertices \(P(2a, 2, 6)\), \(Q(4, 3b, 10)\), and \(R(8, 14, 2c)\), we will use the formula for the centroid of a triangle in three-dimensional space. ### Step 1: Write the formula for the centroid The coordinates of the centroid \(G\) of a triangle with vertices \(P(x_1, y_1, z_1)\), \(Q(x_2, y_2, z_2)\), and \(R(x_3, y_3, z_3)\) are given by: \[ G\left(\frac{x_1 + x_2 + x_3}{3}, \frac{y_1 + y_2 + y_3}{3}, \frac{z_1 + z_2 + z_3}{3}\right) \] ...
