Question

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?

Answer 1

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
