<PRE><B>Question 393374</B>
&lt;br&gt;&lt;font face=&quot;Tahoma&quot;&gt;The easiest way to do these types of problems, is to try to come up with examples that make the choices incorrect. &lt;br&gt;

For example:&lt;br&gt;

a) if I use 2, then 2+1=3 since 3 is not an even number, a must be wrong&lt;br&gt;

c) again, if I use 2, then 4*2+1=9, which is not even! c must be wrong&lt;br&gt;

d) .772 is obviously not an even number&lt;br&gt;

The correct choice must be b!&lt;br&gt;

No matter which choice of integer we use for y, 4y will always be even!&lt;br&gt;

You may hear some arguments that 0 is NOT an even integer, but most, if not all, mathematicians consider 0 to be an even integer.&lt;br&gt;  

And for the sake of this question, they are obviously implying that 0 IS an even integer.&lt;br&gt;

From mathforum.org:&lt;br&gt;

&quot;Integers are the whole numbers, negative whole numbers, and zero... 
The terms even and odd only apply to integers; 2.5 is neither even nor 
odd. Zero, on the other hand, is even since it is 2 times some 
integer: it&#39;s 2 times 0.&quot;&lt;br&gt;

I hope this helps!&lt;br&gt;</PRE>
