$$\frac{\mathrm{4}^{\mathrm{10}} −\mathrm{4}^{\mathrm{9}} }{\mathrm{4}^{\mathrm{11}} −\mathrm{4}^{\mathrm{10}} }=\frac{\mathrm{1}}{\mathrm{4}} \\ $$$${hence}\:\mathrm{4}^{\mathrm{9}} \:{should}\:{be} \\ $$$${at}\:{midpoint}\:{of}\:\:{M}\:{and}\:{D}. \\ $$$${where}\:\:{M}\:{is}\:{midpoint}\:{of}\:{B}\:{and}\:{C}. \\ $$
