The length of a rectangle is 16 units more than its width. The area of the rectangle can be expressed as x^4 – 64.
Which expression represents the width of the rectangle?

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
