What is an arithmetic sequence?

Back

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant.

What is the common difference in an arithmetic sequence?

Back

The common difference is the fixed amount added to each term to get the next term in an arithmetic sequence.

Front

What is a geometric sequence?

Back

A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.

What is the common ratio in a geometric sequence?

Back

The common ratio is the factor by which we multiply to get from one term to the next in a geometric sequence.

How do you find the next term in an arithmetic sequence?

Back

To find the next term, add the common difference to the last term.

How do you find the next term in a geometric sequence?

Back

To find the next term, multiply the last term by the common ratio.
