GCSE Mathematics · key term
A rule that calculates the next term using the current term.
Used by AQA, Edexcel and OCR
Specification A23 · Paper 1, Paper 2, Paper 3
A rule that produces each new term from one or more preceding terms.
Revise: Generating SequencesA term-to-term rule tells you how to move from one term to the next. It must be accompanied by a starting term.
Specification A23 · Paper 1, Paper 2, Paper 3
Revise: Term GenerationA term-to-term rule tells you what to do to the current term to obtain the next one. You need both a starting term and a rule: the instruction ‘add 10’ alone does not tell you where the sequence begins.
Specification 6.06a · Paper 1 (Foundation), Paper 2 (Foundation), Paper 3 (Foundation), Paper 4 (Higher), Paper 5 (Higher), Paper 6 (Higher)
An instruction for finding the next term of a sequence from the current term.
Revise: Generating Sequences and Linear RulesA term-to-term rule tells you how to get the next term from the current one.
A rule that calculates a term using one or more earlier terms.
For a term-to-term rule, state or identify the first term; without it, the rule does not determine a unique sequence.
For a term-to-term rule, count the starting value as the first term: apply the rule once to find the second term.
For a term-to-term rule, give the starting term as well as the instruction for finding the next term.
