7

Step-by-step explanation:

Plug -3 into x and solve

-2(-3) =6

Solve for the rest of the equation

6+1=7

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.
