As you mention “series” in the question I was wondering if something as simple as the term “Arithmetic Progression” is what you're after.
Your first arithmetic progression being $$a_n=n$$ for n=0,1,...,100 and your second being
$$b_n=1000-10n=1000-10a_n.$$
Given your chosen name, I was wondering if your intended application has anything to do with optics? (I ask as my wife is an optician.)
Not really part of the answer but on a lighter note, here's a wonderful quote involving optics from the book “Littlewood's Miscellany”:
From time to time (since 1910) there were moves to get rid of the revolting optics and astronomy set in the Mathematical Tripos. It was discovered that over a period of years no wrangler attempted a question in either subject. An equivalent form of this proposition is that every attempt to do a question in optics or astronomy resulted in a failure to get a 1st.
