Introduction to the tool and how to use it
Online sequence-pattern detector: enter one sequence per line (comma- or space-separated; negative numbers and decimals supported), and it automatically judges whether it is constant, arithmetic, geometric, a finite-difference polynomial, a linear recurrence, or periodic, giving the evidence, general term, and a prediction for the next term.
Classification follows the fixed priority constant → arithmetic → geometric → common sequences → finite differences → linear recurrence → periodic, and outputs only the highest-confidence conclusion; the detection tolerance adjusts how loose floating-point comparison is; tick output differences of all orders to attach a difference table in the evidence column. A line with fewer than 3 terms cannot be classified and prompts you directly.

How to use
- Paste one sequence per line into the input box.
- Set the detection tolerance and choose whether to output differences of all orders.
- Click Run and review the detected pattern, general term, and next-term prediction.
- Copy the results.
