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.

n=9

step-by-step explanation:

7 times a number = 7n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
