Specification References: N6.2 N6.2 Use linear expressions to describe the nth term of an arithmetic sequence.

Candidates should be able to:

Notes

Candidates should know that the n^th term of the square number sequence is given by n².

Examples

1. Write down the sequence where the n^th term is given by 2n + 5.
