Which formula can be used to describe the sequence?, - 4, - 24, - 144, ... f (x) = 6 f (x) = - 6 f (x) = (6) x - 1 f (x) = (-6) x - 1

The formula that can be used to describe the sequence, - 4, - 24, - 144, ... is f (x) = 2/3 (-6) x - 1.

In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the function that relates each real number x to its square x 2.
