$$\left(-\frac{7}{2},\:\frac{3}{2}\right)$$

Using the distance formula, we find: $$\sqrt{\left(-1-\left(-6\right)\right)^2+\left(8-\left(-5\right)\right)^2}\\ \sqrt{194}$$ Using the midpoint formula, we find: $$\left(\frac{-1-6}{2},\:\frac{8-5}{2}\right)\\ \left(-\frac{7}{2},\:\frac{3}{2}\right)$$
