$${a}=\mathrm{2}{m}−\mathrm{1}\wedge\mathrm{1}\leqslant{m}\leqslant\mathrm{14}\wedge{b}=\mathrm{2}{n}−\mathrm{1}\wedge{m}+\mathrm{1}\leqslant{n}\leqslant\mathrm{15} \\ $$$${a}=\mathrm{2}{m}\wedge\mathrm{1}\leqslant{m}\leqslant\mathrm{14}\wedge{b}=\mathrm{2}{n}\wedge{m}+\mathrm{1}\leqslant{n}\leqslant\mathrm{15} \\ $$$$\mathrm{2}\underset{{k}=\mathrm{1}} {\overset{\mathrm{14}} {\sum}}{k}=\mathrm{210} \\ $$
