... If the terms of a series alternate sign and if the terms themselves are approaching 0, then the series converges. Example: 1 – 1/2 + 1/3 - 1/4 + 1/5 - … must converge! (Guess the name of this series.) To what, you ask? Not obvious, since this series is not geometric. Experiment a bit? ...

ON THE NUMBER OF SPECIAL NUMBERS For lack of a better word
... An effective version of the abc conjecture can be used to determine (conjecturally) that there cannot be 12 consecutive special numbers. Suppose not. Let n + 1, n + 2, . . . , n + 12 be all special. Six of these are even, say 2k, 2(k + 1), 2(k + 2), 2(k + 3), 2(k + 4), 2(k + 5). Of these six, at lea ...
