Determine if the following series converges or diverges

Hello! Can you tell me why my answer is wrong? What do I see: the sequence of partial sums diverges to ∞ and so the series also diverges.

Please tell me which answer is correct and why.

task and my answer in the screenshot

Answer 1

Of course sum(1:Inf) is divergent. Either your answer contains a space (which is invisible in a screenshot...) or the test contains a bug.

Ask the person, who has created this question.

I don't know. Did not Ramanujan prove that series converges to -1/12? Only joking of course, as the series diverges for all of us mere mathematical mortals.

But this is why a screenshot is a bad thing to show on answers, since we cannot tell if the word was spelled correctly, if it was corrupted with a noncharacter like a space.

@John D'Errico: Or the programmer made a typo and checks for "divregent". I know another programmer, who swapped two characters without noticing it. Such things happen.

Let's perform a test to decide, if this sum converges.

s = uint64(0);
for k = uint64(1):uint64(Inf)
    s = s + k;
end

Oh dear, you have triggered humor. Time for a break.
