You can count by twos.
Adding 2 to the previous number is possible.
You have to count and skip every other number.
If you started with 0 and counted by twos, the numbers that you would count would be:
0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, and so on.
All of the counts are the same.
