Bailey the dog owns 7 balls. 3 are colored red, 2 are colored yellow, 1 is blue, and 1 is white. If she fetches 3 balls from her collection, how many different color combinations are possible?

i think asking google will you get the answer to that question

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.
