$(2,7),(3,-1),(-5,6)\,$

The formula for finding the centroid or median of a triangle whose vertices are

$(x_1,y_1),(x_2,y_2),(x_3,y_3)\,$ is $\left(\frac{x_1+x_2+x_3}{3},\frac{y_1+y_2+y_3}{3}\right)\,$

Applying the formula, we get

$\left(\frac{2+3-5}{3},\frac{7-1+6}{3}\right)\,$

$\left (0,4\right)\,$

Therefore, the centroid of the triangle formed is at P(0, 4).
