| Feb 17, 2022 at 16:57 | comment | added | Daniele Tampieri | On those matters, I find almost always invaluable have a look at the wonderful book by Konrad Knopp, Theory and application of infinite series, Transl. from the 2nd ed. and revised in accordance with the fourth by R. C. H. Young. (English) London-Glasgow: Blackie & Son, Ltd. XII, 563 p. (1951), Zbl 0042.29203. | |

| Feb 17, 2022 at 6:16 | comment | added | Andreas Blass | @GerryMyerson Indeed, this argument handles any finite number of series, but combining it with a diagonalization we should be able to handle any countable infinity of series. | |
| Feb 17, 2022 at 5:46 | comment | added | Gerry Myerson | Yes. Any finite number of series. | |
| Feb 17, 2022 at 5:30 | comment | added | Michael B | Would $u_n$ and $v_n$ in this solution be sequences of positive reals, thus making $a_n$ also a sequence of positive reals? Using this solution, it seems it could be extended to find a suitable $a_n$ for any number of series we are given. | |
| Feb 17, 2022 at 5:17 | comment | added | Gerry Myerson | Make $u_n/b_n\to\infty$, make $v_n/c_n\to\infty$, let $a_n=\max(u_n,v_n)$. | |
