The undulating number ABAB...ABA with n repetitions of AB followed by one A can be expressed as (AB × 10 2n+1 − BA)/99. For example, 989898989 = (98 × 10 9 − 89)/99; Undulating numbers can be generalized to other bases. If a number in base with even number of digits is undulating, in base it is a repdigit.
