Arithmetic sequence

Definition

A sequence in which the difference between each pair of consecutive terms is constant.

Specification 6.06a · Paper 1 (Foundation), Paper 2 (Foundation), Paper 3 (Foundation), Paper 4 (Higher), Paper 5 (Higher), Paper 6 (Higher)

These are simple arithmetic sequences; comparing their terms with the position numbers helps reveal the rule.
Revise: Generating Sequences and Linear Rules
A sequence in which the difference between each term and the next is constant.
Revise: Arithmetic Sequence Formulae and Subscript Notation

1
For an arithmetic sequence, check that every pair of consecutive terms has the same difference before using a linear nth-term rule.
2
Keep the sign of a negative common difference. For a decreasing arithmetic sequence, the coefficient of $n$ is negative.
