Find the common ratio of the sequence. 4, -4, 4, -

A geometric sequence is built with an initial value and a common ratio.

You start with the initial value , which is the first element of the sequence, and then you build the term by multiplying the previous element by the common ratio . So, the first terms of the sequence are

In this sequence, every element is equal to the previous one, except the sign is opposite. This means that each element is computed by multiplying the previous one by , which is thus the common ratio of the sequence.
