Compare, in the box below, 0.5 and 0.5 when written as fractions. make an observation about these repeating decimals when they are written as fractions. what do you notice that is similar about the original decimals and the numbers in the fractions they become? where do the numbers from the decimals end up in their fractions?

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.
