Arithmetic Sequences Practice

Front

What is an arithmetic sequence?

Back

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

Front

How do you find the common difference in an arithmetic sequence?

Back

The common difference is found by subtracting any term from the subsequent term in the sequence.

Front

Is the sequence 3, 6, 9, 13, 17, 21 an arithmetic sequence?

Back

No, because there is not a common difference every time.

Front

What does the term 'common difference' refer to in an arithmetic sequence?

Back

The common difference is the constant amount added to each term to get to the next term.

Front

What is the common difference in the sequence 5, 7, 9, 11, 13?

How can you determine if a sequence is arithmetic?

Back

A sequence is arithmetic if the difference between consecutive terms is constant.
