Hello okamiyu, I'm very grateful that you spent lots of time on this problem, I really appreciate that. But in this procedure of solving problems, you might have taken the last digit as the unknown for each person, which might generate incorrect answers. For example,
5671,2347この場合娜塔莎は1234/1247/しか確定できない残り5677/3567
ここで娜塔莎は等差数列の情報知っている。この場合567のことを推理できる
この場合阿列克谢は自分が見えないカードの和が奇数時点で2と4があるとしか確定できない。つまり成立
yes Natasha DID get 567 in this case, but can we exclude the situation of 3567? I'm afraid not, I guess when 3 is not seen by Alexei, 3567 can also be a possible case, because what he sees is also 567.
