You can just pretend that ω is finite and plug it into the formula for the partial sum.n∑i=1i=12n2+12n, so ω∑i=1i=12ω2+12ω. If they were to give the ith odd number amount of fish on the ith day (1,3,5,7,9...), then you would have ω2 amount of fish, because n∑i=12i−1=n2. The two links I posted about the handling of infinite divergent series go into greater detail (eg. the question of the starting index).
The links are very on point for my interest thanks for those. Some of it is in rather dense math but alas that is the case when the topic is math.
At one point there is a constuction where in addition to having series of real numbers to define a hyperreal (r1,r2,r3...)=h1 we define a series of hyperreals (h1,h2,h3...)=d1, in order to get a “second tier hyperreal”. So I do wonder whether the “fish gotten per day” is adeqate to distinguish between the scenarios. That is there might be a difference between “each day I get promised an infinite amout of fish” and “each day I get 1 more fish”. That is on day n I have been promised ωn fish and taking it as α∑i=1I am not sure whether α=ω and whether terms like ω2 and ωα refer to the same thing or whether mixing “first-level” and “second level” hyperreals gets you a thing different than mixing just “level 1”s
