marked 'finite harmonic series never sum to an integer' with "Dubious" template
editThis is obviously false, as non-zero constant sequences are harmonic sequences and constant integer sequences sum to integers. I think it should say finite harmonic series of distinct unit fractions, as the lemma the source seems to be a generalization of is about sums of consecutive unit fractions. However I don't know the language the source is written in. Ninjamin (talk) 19:52, 12 September 2019 (UTC)
- Using the German synopsis at the end the quoted source, I was able to verify my guess (or a very slight variation of it). It says, if a, d and n are positive integers, then is never an integer. I will adjust the article. Ninjamin (talk) 09:44, 13 September 2019 (UTC)

Sum of "n" Terms in an HP
editWhy isn't the sum of n terms in a HP added.
it is 1/d * log{[2n+(2n-1)d]/[2a-d]} SYED BADIUDDIN ANAS (talk) 11:36, 24 March 2024 (UTC)
