What is the common ratio between successive terms in the sequence? 2, - 4, 8, - 16,

the answer is f (x) = n * (-2)

ratio is the wrong word to use, it is for contolled variation in probability. a sequence is controlled by what is known as a function - f (x) is the symbol for a function

Step-by-step explanation:

the following number of the previous one in the sequence is derived by the function f (x) = n * (-2)

2 x - 2 = - 4 (positive x negative = negative)

-4 * - 2 = 8 (negative x negative = positive)

8 x - 2 = - 16 (positive x negative = negative)

so in the sequence, the trend of -, + double will go on
