For example, can you tell in advance what the sum of all
numbers [1..n] is, without actually adding them all up ?

I fail to understand how that is relevant to the problem in question.
Yes, being able to calculate the sum of integers 1-n without doing an
explicit loop is faster, but it doesn't change the O(n) complexity of
the requested algorithm.
