Question 777379
Even numbers are of the form 2N where N starts at 1. So 3 consecutive numbers are 2N, 2N+2, 2N+4. We just need to solve for N. 

2N+(2N+2)+(2N+4)= 6N+6=6216,  6N=6210, N=1035 and our numbers are 

2070,2072,2074

ANS: 2074

Note - the 'easy way' to solve is 6216/3 = 2072 which is the middle number, and +2 for last house, -2 for first. Teachers like the first answer better.
