you're asking the wrong question. a SEQUENCE, by default, is IN ORDER. you cannot change the order of a sequence unless you are explicitly instructed to do so by the problem.
if the profits of a business, in sequence, for a few consecutive years are $1 million, $4 million, -$2 million, $3 million, and $0, then you can't just rearrange those into increasing order.
the question is, "is there anything here that TELLS me to re-order the sequence?"
the answer is no.
therefore, you don't re-order the sequence.
that's pretty much it.
