How do you answer this mathswatch question?

see explanation

Step-by-step explanation:

(a)

AB = AO + OB = - a + b = b - a

(b)

OP = OA + AP = a + (b - a ) = a + b - a = a - 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.
