Pair the numbers off into groups of two. Then, in each set, the first number represents an ordinary number, while the second is the number of "digits" the Roman numeral representation of the number includes.

So in (1,1), the RN for 1 is (i), which is 1 letter, while in the pair (47,5), the RN for 47 is (XLVII), which is 5 letters long. Following this, the first unknown is 2 (XX), the second is 2(LI), and the third is 0, the only number properly created in the nineties with just two symbols (I believe that the correct representation of 99 is XCIX, not IC). The first number in each pair is simply chosen to disguise the relation.
