How it works:
- A sequence of numbers appears with a pattern (e.g., 2 → 4 → 6 → 8 → ?)
- Identify the rule connecting the numbers
- Select the next number that continues the pattern
- Get instant feedback and move to the next sequence
Pattern types by difficulty:
- Easy: Simple addition (+1, +2, +3, +5) — like 5, 10, 15, 20
- Medium: Larger gaps, subtraction, doubling (×2), alternating patterns
- Hard: Variable gaps (+1, +2, +3...), multiply then add, Fibonacci-style, squares
Session types:
- Time-based: Solve as many sequences as possible in 60 seconds
- Trial-based: Complete 20 sequences as accurately as possible
Tips:
- Calculate the difference between consecutive numbers first
- Check if differences are constant (arithmetic) or changing (growing/shrinking)
- Look for multiplication patterns if differences seem too large
- Some patterns alternate between two different rules
