Choose a rule that fits every transition
Which rule explains every transition in 2, 5, 11, 23?
Candidate-rule test
A compound rule must reproduce every next term
Proposed ruleMultiply by 2, then add 1
- 2→×2 + 1→5Fits
- 5→×2 + 1→11Fits
- 11→×2 + 1→23Fits
ConclusionThe same compound operation explains all three transitions.
A rule that explains only one jump is a hypothesis, not a verified description of the shown pattern.
