help me to do it with step by step​

Step-by-step explanation:

b.solution

we should add q to get p+q

c.solution

we should subtract 7a to get 5a

d.solution

we should subtract 2y to get 3x-2y

Q should be added to P to get p+q

7a should be subtracted from 12a to get 5a

2y should be subtracted from 3x to get 3x-2y

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.
