If w,x,y,z are consecutive positive integers ; then which of the following is always even?
[1] w*x+(y+2)^2*z
[2] w^x + z^y
[3] 6z^2	Choose the correct choice from the following options:
A) 1  B) 2  C) 3  D) 1 and 2  E) 1 and 3
Plug in some numbers   w = 1   x = 2   y = 3   z = 4   Check the options -   [1] w*x+(y+2)^2*z = 1*2 + (3+2)^2 * 4 =&gt; 2 + 25*4= 
<gadget id="calculator">2 + 25*4</gadget>
<output>102</output>
102{ Not an odd Number }   [2] w^x + z^y= 1^2 + 4^3 =&gt; 1 + 64= 
<gadget id="calculator">1 + 64</gadget>
<output>65</output>
65{ Odd number }   [3] 6z^2=6*4^2 even   [1] and [3]   1 and 3
<result>E</result>
