:Especially in the lead, but more generally in all Wikipedia articles, formality needs to take a back seat to understandability. It does not make it any more accurate, rigorous, or correct to express the same thing in notation rather than words; it merely makes it harder for the uninitiated to understand. We should be working to make mathematics understandable to all, not building ivory towers of obscurantism to keep others out. See [[WP:TECHNICAL]].
:As for your re-derivation of i, that one is messy enough that a formula rather than words probably is the right way to express it. It's
::<math>i = \left\lfloor \sqrt{2(k+1)} - \frac{1}{2}\right\rfloor.</math>
:But you should probably find a [[WP:RS|reliable source]] for an equivalent formula before adding it to the article rather than taking my word for it. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein|talk]]) 05:30, 30 October 2019 (UTC)
