(x-y)= 5. give. -------1
(x^2- y^2) = 65.
(x+y)× (x-y) = 65.
(x+y)× 5 = 65.
(x+y) = 13. ---- 2
by solving 1 & 2 .......,
x=9 , y=4..
therefore, the largest number is 9.

Let the first no. be x
so other no.=x+5
A/q
(x+5)^2-x^2=65
x^2+2×5x+5^2 -x^2 =65
x^2 +10 x+25 - x^2 =65
10x=65-25
x=40/10
x=4
larger no.=x+5
=4+5
=9
so other no.=x+5
A/q
(x+5)^2-x^2=65
x^2+2×5x+5^2 -x^2 =65
x^2 +10 x+25 - x^2 =65
10x=65-25
x=40/10
x=4
larger no.=x+5
=4+5
=9
