What is the general form of a geometric sequence?

Back

A geometric sequence is defined by the formula a_n = a * r^(n-1), where 'a' is the first term and 'r' is the common ratio.

How do you find the nth term of an arithmetic sequence?

Back

The nth term of an arithmetic sequence can be found using the formula a_n = a + (n-1)d, where 'a' is the first term and 'd' is the common difference.

What is the common difference in an arithmetic sequence?

Back

The common difference is the difference between consecutive terms in an arithmetic sequence.
