Number Sequence Finder
Enter a number sequence and identify the pattern — arithmetic, geometric, or quadratic — then predict the next terms.
Pattern & Next Terms
Number Sequence Finder identifies the pattern in your sequence and predicts the next terms.
Arithmetic Sequence: Constant difference between terms.
2, 5, 8, 11, 14... → common difference = 3
Geometric Sequence: Constant ratio between terms.
3, 6, 12, 24, 48... → common ratio = 2
Quadratic Sequence: The second differences are constant.
1, 4, 9, 16, 25... → differences: 3, 5, 7, 9 → second diff = 2
Formulas:
- Arithmetic:
aₙ = a₁ + (n-1)d - Geometric:
aₙ = a₁ × rⁿ⁻¹ - Quadratic:
aₙ = an² + bn + c
