When asked to find the n-th term of a linear sequence, you are asked to find the rule or the formula that allows you to find any term in the sequence.

This formula is of the form** an + b**; where the following criteria must be met:

- ‘
**a**‘ is any positive or negative number (**but not 0**) - ‘
**b**‘ is any positive or negative number (**can be 0**) - ‘
**n**‘ must be a positive integer (**whole number**)

To find the n-th term for a sequence you need to go through a few steps.

## EXAMPLE I – Sequence in increasing order

## EXAMPLE II – Sequence in decreasing order
