Inspired by the newly observed three resonances X(1835), X(2120), and X(2370), in this work we systematically study the two-body strong decays and double pion decays of {eta}(1295)/{eta}(1475), {eta}(1760)/X(1835), and X(2120)/X(2370) by categorizing {eta}(1295)/{eta}(1475), {eta}(1760)/X(1835), X(2120), and X(2370) as the radial excitations of {eta}(548)/{eta}{sup '}(958). Our numerical results indicate the followings: (1) The obtained theoretical strong decay widths of three pseudoscalar states {eta}(1295), {eta}(1475), and {eta}(1760) are consistent with the experimental measurements; (2) X(1835) could be the second radial excitation of {eta}{sup '}(958); (3) X(2120) and X(2370) can be explained as the third and fourth radial excitations of {eta}(548)/{eta}{sup '}(958), respectively. The predicted two-body decay patterns of {eta}(1295)/{eta}(1475), {eta}(1760)/X(1835), and X(2120)/X(2370) and their double pion decays should be useful for further testing the conventional meson assignment to {eta}(1295)/{eta}(1475), {eta}(1760)/X(1835), X(2120), and X(2370).
