Help me on this question, I'll give brainlist for the correct answer.

Step-by-step explanation:

The first expression has value 12

The second expression has value -6

The third expression has value

4

And finally the forth expression has value 1.14

((13 + 7) = 20

(12+4) = 16

16/ (20 - 16)= 16 / 4

16/4 = 4

c the third one

Step-by-step explanation:

((13 + 7) = 20

(12+4) = 16

16/ (20 - 16)= 16 / 4

16/4 = 4

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.
