Feb 25, 2019 at 21:43 | comment | added | Judah Greenblatt | Counter example where there are an infinite number of infinite arithmetic progressions and NO progression has the difference equal to the initial term. for k from 1 to inf { S(k) = 2^k * n + 2 ^ (k-1) for n from 0 to inf } S(1) is odd integers; S(2) is 2, 6, 10 - twice an odd integer; and continues for powers of 2. In all cases the initial term is the difference / 2. | |

Feb 25, 2019 at 15:27 | comment | added | VRS | Sorry I should’ve asked for counter example also. I have edited the question now. The source is the variant mentioned below the main question which is an exercise from “A Walk Through Combinatorics”. | |
