Question 268543
Let x, x+2, x+4 & x+6 be the 4 numbers.
x+x+2+x+4+x+6=23,672
4x+12=23,672
4x=23,672-12
4x=23,660
x=23,660/4
x=5,915 is the lowest house number.
5,915+2=5,917 is the second house number.
5,915+4=5,919 is the third house number.
5,915+6=5,921 is the largest house number.
Proof:
5,915+5,917+5,919+5,921=23,672
23,672=23,672
