I require some guidance on the correct terminology for the following:
In a series of numbers...
first / last members - ordinal / terminal (or other)?
next / previous members - ordinal / adjacent (or other)?
So far I have referred to them all as ordinal (as in 1st, 2nd, 3rd, ..., last), but I want to distinguish between first/last/next/previous.
I only ask because I wish to properly name methods in some program code I'm developing.
I am not a mathematician or statistician, etc, just a novice.
Thanks for any help.
