The average (arithmetic mean) of the even integers from 24 to 48 inclusive is how much greater than the average (arithmetic mean) of the even integers from 12 to 24 inclusive? Pick.
A) 14	B) 16	C) 18	D) 20	E) 22
So, according to A mean of a set of even numbers from 24 to 48 =(24+48)/2= 
<gadget id="calculator">(24+48)/2</gadget>
<output>36</output>
36 and mean of a set of even numbers from 12 to 24=(12+24)/2= 
<gadget id="calculator">(12+24)/2</gadget>
<output>18</output>
18   Difference=36-18= 
<gadget id="calculator">36-18</gadget>
<output>18</output>
18   Answer: 18.
<result>C</result>
The average (arithmetic mean) of the even integers from 24 to 48 inclusive is how much greater than the average (arithmetic mean) of the even integers from 12 to 24 inclusive?
