Center of a circle is a midpoint of line connecting two endpoints so center is:
(12,-14) (2,4) we divide those two points by two
C(a,b)- center
C(a,b)=((12+2)/2),(-14+4)/2)=(7,-5)
Radius is the distance from the center to any point on the circle:
we take point (2,4)
r=

Let the first integer be . So, the next even number is
Let's translate the formula: the square of the second is , twice the first is
. So, the equation is
Expand the square to get
The solutions to this equations are
So, the possible consecutive even numbers are
