A geometric progression of the masses of elementary fermions

We have studied the mass distribution of three generations of quarks and leptons, and found that when the elementary fermions are arranged in a certain order, a geometric series can be used to describe their mass distribution. Based on this mass distribution law of elementary fermions, combined with the observational data of neutrino oscillation, the mass of neutrinos can be estimated approximately. The results show that the sum of the neutrino masses is 0.06 eV in the normal neutrino mass ordering picture.
