What is an arithmetic sequence?

Back

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

Front

What is the common difference in an arithmetic sequence?

Back

The common difference is the constant amount that each term in the sequence increases or decreases by.

Front

Is the sequence 17, 9, 1, -7 an arithmetic sequence?

Back

Yes, the sequence is arithmetic because the common difference is -8.

Front

How do you determine if a sequence is arithmetic?

Back

A sequence is arithmetic if the difference between any two consecutive terms is the same.

Front

What is the formula for the nth term of an arithmetic sequence?

Back

The nth term can be found using the formula: a_n = a_1 + (n-1)d, where a_1 is the first term and d is the common difference.
