X, 2010, 2061, 3001 in Arabic numbers or their equivalents in Roman numerals (trying to avoid a complete spoiler) did NOT seem to make a series, either in terms of addition, number / letter patterns or anything else to me.
Google a list of his works. I have to say, I'd only ever heard of the famous one. In your list of numerals, apart from the years you've given you should also have MM. This requires another single 'missing' numeral.
I don't know where you get your X from at the beginning, jazzlover, but otherwise your numbers are correct. Have you got the unclued entries in the top and bottom rows because they will explain a lot? This is not a mathematical series; the puzzle commemorates someone's anniversary.
Jazzlover, you need to see what the books are about to understand the logic. Eg, 2061 because it is about the return of Halley's comet, due in that year.
