10. when you add the same number to both sides of an inequality, is the inequality still true? explain how you know your statement holds for subtracting the same number?

the inequality is true because if you subract the same number from both side you will get the original inequality equation

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.
