The sum of the second and seventh numbers in a list of consecutive even numbers is 114. What is the sum of the first 3 numbers?
------------------
2 thru 7 --> 6 numbers
114/2 = 57, the center of the 6, so 3 are less and 3 are more than 57
--> 52, 54, 56, 58, 60, 62
52 is the 2nd, --> 50 is the 1st
50 + 52 + 54 = 156
