No. Note that any odd number [math]N[/math] can be written in the form [math]N=2a+1[/math] for some integer [math]a[/math], then adding three of these becomes [math]2(a+b+c) + 3[/math] which is always odd as the sum of an even number and an odd number is always odd (which is something you should definitely prove, yourself).
