The fifth term (n=4) would be particularly problematic.
Andrew Leaver-Fay has an Erdős number of 3, and cowrote www.nature.com/nature/journal/v466/n7307/full/nature09304.html. One of the other authors on that paper is "FoldIt Players".
Therefore, to get a full accounting of how many people have an Erdős number of 4, we'd need to find out exactly what the cutoff date was on data collected for the article, and find out exactly how many people played FoldIt prior to that date. I'm curious as to whether the authors have that precise number on hand - it would be fascinating.
My wife used to be a biologist, and her pointing me to this game but not trying it out herself was how I ended up with a lower Erdős number than hers.

Dear Sequence Fans,
another perhaps not so great sequence idea:
Number of people with Erdős number n. With offset 0, the
sequence starts 1,
511. The next term is not currently fixed.
For more information, see https://en.wikipedia.org/wiki/Erd%C5%91s_number
I expect this sequence not to be acceptable, so I am just
throwing the idea
here in case anyone thinks this is interesting.
