Wouldn't you expect to get a greater answer for the second one than for the first one?

No, the second one is pairwise the first is the whole list minus the second list. I expect the first one to be larger.

But if you look at both pairwise, the first one can both increase and decrease, but the second one can only increase, so I would expect the second one to be greater.

The pairwise one can never be greater than 5. The other? Who knows!

What about

(1,6)

(1,6)

(1,6)

The sum is 30!

That is why I did not want to discuss two sums. That sum does not exist so why are we talking about it?

The pairwise sum. That one comes from the problem. It is an average value. It is <=5.

There is no reason for it to be <=5. Only the summands are <=5.

6 - 1 = 5. That is the biggest difference. If you add up a ton of numbers that are 5 or less their average will be 5 or less.

But we don't take the average of the differences!

Yes we do. The original problem was an average. gAr and I agreed on that. The series you came up with here is something else. It has nothing to do with either problem. Why discuss it all?
