let first natural even number be x
next consecutive number is x+2
by given condition ,
x^2 + (x+2)^2 = 244
x^2 + x^2+ 4x + 4 = 244
2x^2 + 4x + 4 =244
2x^2 + 2x + 4 - 244 = 0
2x^2 + 2x - 240 = 0
x^2 + x - 120 = 0
x^2 + 12x 10 x - 120 = 0
x ( x + 12 ) - 10 ( x + 12 ) = 0
( x + 12 ) ( x - 10 ) = 0
( x + 12 ) = 0 or ( x - 10 ) = 0
x = - 12 or x = 10
x = - 12 not possible
so ,
x = 10
numbers are 10 and 12
next consecutive number is x+2
by given condition ,
x^2 + (x+2)^2 = 244
x^2 + x^2+ 4x + 4 = 244
2x^2 + 4x + 4 =244
2x^2 + 2x + 4 - 244 = 0
2x^2 + 2x - 240 = 0
x^2 + x - 120 = 0
x^2 + 12x 10 x - 120 = 0
x ( x + 12 ) - 10 ( x + 12 ) = 0
( x + 12 ) ( x - 10 ) = 0
( x + 12 ) = 0 or ( x - 10 ) = 0
x = - 12 or x = 10
x = - 12 not possible
so ,
x = 10
numbers are 10 and 12
