Example next step from a mock review
Sequences & series · Finite states, cycles and recurrence invariants
If a recurrence question was slow or incorrect, the next session can repair that exact decision: recognise the full state, prove the cycle, then apply it without a prompt in matched practice.
- Study why a repeated full state forces the future to repeat
- Contrast first-order values with second-order ordered pairs
- Return to a linked difficulty 4/5 recurrence question
