# Counting by 4s The concept of counting by 4s is used in the table of 4. You can count by fours by adding 4 to the previous number.

If you start with 0 then the numbers counting by four are
0,4,8,12,16,... and so on

If you start with 1 then the numbers counting by four are
1,5,9,13,17,... and so on

Note: If the starting number is odd then the numbers formed by counting by 4's are odd. If the starting number is even then all the counting numbers will be even.
