| Dec 27, 2023 at 18:47 | comment | added | Christian Remling | As in Iosif's answer below, the optimal arrangement is to take the final sign as $+$ and all the others as $-$. By the way, your question would have been much better suited (and likely better received at) math.stackexchange.com . | |
| Dec 27, 2023 at 18:44 | comment | added | john22445 | Yes, do you have any idea on how to get An? | |
| Dec 27, 2023 at 18:19 | comment | added | Christian Remling | This has nothing to do with probability since every arrangement has positive probability, so you are really asking: What is the smallest possible value (in absolute value) of $\sum \pm 4^n$ ? | |
