Subtract: x^2+4xy −3y^2 from 2x^2−5xy+y^2

2x^2−5xy+y^2 - (x^2+4xy −3y^2)

= 2x^2−5xy + y^2 - x^2 - 4xy + 3y^2

= x^2 - 9xy + 4y^2

answer

x^2 - 9xy + 4y^2

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.

probably the last option
