Explain how you know which numbers to write.
Answer:

Let’s take a look at the counting tracks. Notice the first row having 1 to 10. The second row has 11 to 20. Each number begin with 1, the second digit increases by 1 until the last column. In the third row, the pattern is the same only difference is the first digit is 2 instead of 1 and the second digit is increased by 1 until the last column. Notice that the second digit in each column is the same. Let’s skip down to 100 and the pattern continues. Now we have three-digit numbers like 101, 102, 103, 104, 105 and so on… and every third digit is increased by 1.
