A/b + c/ b=?

answer choices are:
1) -ab/c
2) b/ac
3) ad/CBS
4)a+c/b
5) ab/c^2
6)ab+c/b

4)a+c/b

Step-by-step explanation:

a/b + c/ b

The denominators are the same, so we can add the numerators

(a+c)/b

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.
