Answer:
Step-by-step explanation:
let the number be n
the next odd number would be n+2(as n+1 would be even)
n^2+(n+2)^2 = 394
n^2+n^2+4n+4=394
2n^2+4n=390
n^2+2n=195 (after dividing by 2 on both sides)
n^2+2n-195=0
n^2+15n-13n-195=0
n(n+15)-13(n+15)=0
n=13,(-15)
but if n= -15,
(-15)^2 + (-17)^2=514
thus,
n=13
