Algorithms that Generate Number Sets (AC9M4N09)
follow and create algorithms involving a sequence of steps and decisions that use addition or multiplication to generate sets of numbers; identify and describe any emerging patterns
Choose a learning activity. Practice and Test use short shuffled attempts. Repeat quiz practice to access more of the full question bank.
Unit focus
- An algorithm is a precise sequence of instructions. Repeating addition or multiplication rules can generate number sets, while decisions route inputs through different steps and produce patterns worth explaining.
- Use this routine: Define input → Follow ordered steps → Apply decision → Record output set → Identify pattern → Test generalisation.
- Watch for steps reordered: Algorithms depend on exact sequence.
