P2.4.3 - Increasing sequences, decreasing sequences and periodic

Increasing sequences, decreasing sequences and periodic sequences.

Use increasing sequences, decreasing sequences and periodic to connect the rule to the data and decision in the question.

This matters because increasing sequences, decreasing sequences and periodic determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply increasing sequences, decreasing sequences and periodic to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: Increasing sequences, decreasing sequences and periodic is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
