Answer by JulietG(1812)   (Show Source):
You can put this solution on YOUR website! Since they're even, they must end in 0,2,4
There's a shorter way to do it, but it will be easier to see it by listing.
02
04
10
12
14
20
24
30
32
34
40
42
Note that the odd numbers have three possibilities in the tens column, but the even have only two, due to non-repetitiveness.
