## Question:

For the arithmetic sequence 2/3, 1/15, -8/15,

a. determine the common difference, and

b. find the next three terms of the sequence.

The common difference between the arithmetic sequence is the difference of any two consecutive terms. That is:

{eq}d = a_{n} - a_{n-1} {/eq}

In arithmetic sequence each term is the sum of its previous term and common difference.
