Step-by-step explanation:

Pythagorean Theorem :

a^{2} + b^{2} =c^{2}

replace a and b

5^{2} + 12^{2} =c^{2}

25+144=c^{2}

169=c^{2}

13=c

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.
