Let M be a weighted binary matroid and UJ~ < . < w,,, be the increasing sequence of all possible distinct weights of bases of M. We give a sufficient condition for the property that Wl,..., wm is an arithmetical progression of common difference d. We also give conditions which guarantee that wi+l -w
