The side of an equilateral triangle is 12. Its area is Select one:
a. 72
b. 48
c. 144
d. 36 square root 3

A≈62.35

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.
