What are the next three terms of iii vi xi xviii xxvii in roman numerals showing the nth term formula?

Answer 1

If by using the formula: nth term = n2+2 the sequence is 3 6 11 18 27 38 51 66.

Then it follows that by using the same formula the sequence is III VI XI XVIII XXVII XXXVIII LI LXVI in Roman numerals.

Answer 2

The given sequence follows a pattern. Each term is obtained by adding n-1 to the previous term. Using the nth term formula, the next three terms would be xxxvi, xlvii, and lviii.
