Define a Geometric Sequence.

Back

A sequence of numbers in which 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 formula for the nth term of an Arithmetic Sequence?

Back

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