Answer:
let the numbers are x and x+2
so,
x^2+(x+2)^2=244
=> x^2+x^2+4x+4=244
=> 2x^2+4x+4=244
=> 2(x^2+2x+2)=244
=> x^2+2x+2=244/2=122
=> x^2+2x+2-122=0
=> x^2+2x-120=0
=> x^2+12x-10x-120=0
=> x(x+12)-10(x+12)=0
=> (x+12)(x-10)=0
x+12=0
=> x=-12
x-10=0
=> x=10
so the numbers are 10 and 12
or the numbers are -10 and -12
