The number that comes after XVI is XVII.
XVI is the Roman numeral for 16, and XVII represents 17.
Roman numerals follow a specific pattern:
- I = 1
- V = 5
- X = 10
- L = 50
- C = 100
- D = 500
- M = 1000
When a smaller numeral is placed to the left of a larger one, it means subtraction. For example, IV is 4 (5-1), IX is 9 (10-1), and XL is 40 (50-10).
Therefore, XVII is simply 10 + 5 + 2, or 17.
