I can appreciate that any term in an arithmetic sequence can be expressed in terms of its position in the sequence and generate any term.

Arithmetic/linear sequence - An arithmetic (or linear) sequence is a sequence where the difference between successive terms is a constant
Pupils assume a sequence is arithmetic and only check the first few terms.
Encourage pupils to check all the terms of a sequence they are given to check that the pattern they think they have spotted is continuing.
