The set \(\{2, 4, 6, \dots, n\}\) contains the positive consecutive even integers from 2 through \(n\). When one of the integers from the set is removed, the average of the remaining integers in the set is 28. What is the least possible value of \(n\)?

I got that the sum of the set is \(n+n^2\) but I don't know if that will help me.
