Difficulty: Easy
Correct Answer: XVII
Explanation:
Introduction / Context:
Roman-numeral sequences often hide a simple arithmetic pattern when converted to Arabic numbers. Here the steps between terms are constant.
Given Data / Assumptions:
Concept / Approach:
The Arabic values form an arithmetic progression with common difference +3.
Step-by-Step Solution:
5 → 8: +38 → 11: +311 → 14: +3Therefore the next is 14 + 3 = 17Convert 17 to Roman numerals → XVII
Verification / Alternative check:
17 → 20 is also +3; 20 in Roman is XX, matching the series.
Why Other Options Are Wrong:
Common Pitfalls:
Working in Roman numerals directly can obscure the simple +3 pattern; convert to Arabic first.
Final Answer:
XVII
