The sequence you've provided appears to be a mix of Roman numerals and Arabic numerals. Here's the sequence with the numerals converted to Arabic numerals:

XIX (19) IX (9) XVII (17) XIV (14) XV (15) XVI (16)

It seems like you're mixing Roman numerals (XIX, IX, XVII, XIV, XV, XVI) with Arabic numerals (19, 9, 17, 14, 15, 16). If you'd like to continue the sequence using either Roman numerals or Arabic numerals, please specify your preference, and I'll be happy to assist you further.
