Find the 6th term of the arithmetic sequence. -7, -17, -27, -37...... The 6th term is _____.

Arithmetic Sequence

An arithmetic progression (AP), also called an arithmetic sequence, is a sequence of numbers that differ from each other by a common difference {eq}(a_1, a_1+d, a_1+2d, a_1+3d, ...) {/eq}. For example, the sequence 2, 4, 6, 8, ... is an arithmetic sequence with the common difference 2.

We can find the common difference of an AP by finding the difference between any two adjacent terms i.e. {eq}a_2-a_1 {/eq}.
