Can I say:
By turns: To describe the situation that the order of the sequence keeps repeated, like ABCD ABCD ABCD.......
Therefore, if there are four kids, they need to do the dishes one by one in a predetermined order, A to B to C to D.
Then, I say that A, B, C, D do the dishes by turns.
In turn: To describe the situation that the order of the sequence is not necessarily repeated, like ABCDEFG........
I say that the Olympic games will be hosted by the elected cites in turn, since the order is not predetermined and won't be repeated.
Is that correct?
It makes sense to me.
(Say: "The order of sequence IS repeated.")
