Multiply the years (factor) by the receding amount, 3cm, (constant) BAM answer.
If the pattern continues, so that each term is separated by a distance of 3, then the sequence is given by the recursive rule
From this definition, we can write 
in terms of 
:
and so on, up to
(notice how the subscript on <em>a</em> and coefficient on 3 add up to <em>n</em>)
or
