Your answer would be 22 because it says "sum" which means add. Then it says "of three consecutive even numbers" which means you're going to be adding three of the same even number to get 66. 22 is an even number, so let's try it out: 22 + 22 + 22 = 66. (You can also divide 66 by 3.) 22 is the cOrrect answer.
