Write the integers, beginning with 1, in roman numerals (using capital letters in a sans-serif font.) The number of strokes used to write each consecutive roman numeral is the sequence given above.
Since the sequence takes you from 1 (I) to 21 (XXI), the next terms are 22, 23, 24, 25, and so on, or XXII, XXIII, XXIV, XXV, etc. That makes the next terms in the sequence 6, 7, 7, 6, etc.
Now, my question is: what is the 90th term of the sequence?
