Examples of what pupils should know and be able to do
Generate quadratic sequences from a range of contexts.
- Find the first few terms of the sequence; describe how it continues using a term-to-term rule.
- Use algebraic expressions to describe the nth term, justifying them by referring to the context.
- When appropriate, compare different ways of arriving at the generalisation.
