WebIn number theory, Bertrand's postulate is a theorem stating that for any integer >, there always exists at least one prime number with < < A less restrictive formulation is: for every >, there is always at least one prime such that < <. Another formulation, where is the -th prime, is: for + <. This statement was first conjectured in 1845 by Joseph Bertrand (1822–1900).
