Use and adapt further examples from FTM(S)
pp. 154-157- Acrobat pdf document (52Kb) for pupils to
generate and explore terms of sequences.
Keep to linear sequences and get pupils to build up the pattern using equipment
or by drawing on paper.
Help pupils to see the link between a constant difference in the sequence
and the multiplier in the nth term.
