N6.2 Use linear expressions to describe the nth term of an arithmetic sequence.
Candidates should be able to:
work out an expression in terms of n for the nth term of a linear sequence by knowing that the common difference can be used to generate a formula for the nth term
Notes
Candidates should know that the nth term of the square number sequence is given by n2.
Examples
Write down the sequence where the nth term is given by 2n + 5.
