85 in words: Eighty-five
Eighty-five in Roman numerals is LXXXV, and it is the cleanest of its neighbours: L (50) plus XXX (30) plus V (5), with no subtraction anywhere. Every letter simply adds on, so once you can read LXXX as eighty, the final V for five finishes it.
That lack of a subtractive pair makes LXXXV easier to write from memory than LXXXIV just below it or LXXXIX just above. If you are lining up a run of dates or numbering a series, it is a useful one to know on sight.
