Used by Edexcel

Specification A23 · Paper 1, Paper 2, Paper 3

A term's position tells you where it sits in the list. The first term has position 1, the second has position 2, and so on. Position and value are different: in this sequence, the term at position 2 has value 6.
Revise: Term Generation

1
Write position numbers above the terms to keep track of which term you are finding.
2
In a position-to-term rule, substitute the position number, not the value of the previous term.
