let the first odd number be x
second odd no. consecutive to x = x+2
ATQ,
x^2 +(x+2)^2 = 16( x+x+2) + 2
x^2 + x^2+4x+4 = 32x + 32 + 2
x^2 + x^2+4x+4 = 32x + 34
2x^2+ 4x+ 4 = 32x + 34
Dividing both sides by 2,
x^2 + 2x + 2 = 16x + 17
x^2 - 14x - 15 = 0
x^2 - 15x + x - 15 = 0
x(x-15) +1(x-15) = 0
(x+1)(x-15) = 0
x-15 = 0( since both are natural x= -1 is not valid)
x = 15
second no. = x+2 = 15+2= 17
