(I bet you will send me to english.stackexchange.com and they will send me back here)
I will use an example - I have two lists of integers:
- list A: 0, 4, 8, 12, ...
- list B: 2, 6, 10, 14, ...
I'm looking for a neat word to clearly differentiate these lists when talking to a colleague who doesn't really have a maths mindset. My intuition is:
- list A is "even multiples of 2"
- list B is "odd multiples of 2"
I tried to google this sort of wording, but I get mixed results:
- Some results use these words the way I came up with, which is promising;
- Some results would only call n and odd multiple of k if n itself is an odd number (and thus k is odd too);
- Some results also use the word "odd" as another word for "unusual" (which is odd, haha)
So what is the term for multiples made by using an odd/even factor?
Hopefully by now you can see why I struggled to come up with a good title for this question.
EDIT: A comment from GerryMyerson hints that I probably used an unfortunate k in my example. I'm after a word that will work for any k, whether or odd or even (although "pateksan's odd multiples" of odd k are actually odd numbers). So for example list A might be 0, 8, 16, 24, ... and list B might be 4, 12, 20, 28, ...
