How to Use the Sequence Pattern Analyzer
Type your sequence as comma-separated numbers and the analyzer automatically identifies the pattern and predicts the next 3 terms. Works with arithmetic, geometric, Fibonacci-like, square, cube, and quadratic sequences.
Detectable Patterns
Arithmetic: 1, 3, 5, 7 → common difference 2
Geometric: 2, 6, 18, 54 → common ratio 3
Fibonacci: 1, 1, 2, 3, 5, 8 → each term = sum of previous two
Perfect squares: 1, 4, 9, 16, 25 → n²
Perfect cubes: 1, 8, 27, 64 → n³
Quadratic: 1, 3, 6, 10, 15 → triangular numbers
FAQ
Can I use negative numbers or decimals?
Yes. Both are fully supported. Example: −3, −1, 1, 3, 5 is detected as an arithmetic sequence with d = 2.
What if multiple patterns fit?
The analyzer checks in priority order: arithmetic → geometric → Fibonacci → squares → cubes → quadratic. The first matching pattern is returned.
