House numbers on one side of a street are consecutive even integers. the sum of the first three house numbers on the street is 6216. what is the number of the third house?

Consecutive even integers ... x, x + 2, x + 4

x + (x + 2) + (x + 4) = 6216

3x + 6 = 6216

3x = 6216 - 6

3x = 6210

x = 6210/3

x = 2070

x + 2 = 2070 + 2 = 2072

x + 4 = 2070 + 4 = 2074 <===house 3
