A park in the shape of a rectangle is 18 miles long and 24 miles wide. How much shorter is your walk if you walk diagonally across the park instead of along the two sides of it?

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.
