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

Back

The common difference is found by subtracting any term from the term that follows it.

Front

How do you find the common ratio in a geometric sequence?

Back

The common ratio is found by dividing any term by the term that precedes it.

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

Back

The formula is a_n = a_1 + (n-1)d, where a_1 is the first term and d is the common difference.

What is the formula for the nth term of a geometric sequence?

Back

The formula is a_n = a_1 * r^(n-1), where a_1 is the first term and r is the common ratio.
