PatternLab
Automatically finds arithmetic or geometric structure.
Most simple number patterns are either arithmetic (constant difference between terms) or geometric (constant ratio between terms) — checking both is usually the fastest way to spot the rule behind a sequence.
Spotting the underlying rule lets you predict future terms without listing every one — useful for everything from IQ-test-style sequence questions to noticing a real trend in data.

Check consecutive differences
5−2, 8−5, 11−8, 14−11= 3, 3, 3, 3All differences equal → arithmetic sequence
common difference = 3= arithmeticPredict the next term
14 + 3= 17Result
Pattern: Arithmetic (common difference 3)
This sequence follows a constant-difference (arithmetic) pattern — the next term should be 17.
