The greatest two-digit number is 99. Adding 1 to the greatest two-digit number will result in 99+1 =100. That is, it results in the smallest three-digit number.
Proceeding in this way, we can have the following table.
| Greatest number | Adding 1 | Smallest number |
| 9 | +1 | =10 |
| 99 | +1 | =100 |
| 999 | +1 | =1000 |
| 9999 | +1 | =10000 |
| 99999 | +1 | =100000 |
| 9999999 | +1 | =1000000 |
| 9999999 | +1 | =10000000 |
Thus, the resultant pattern becomes.
Greatest single(1) digit number + 1 = smallest 2-digit number.
Greatest 2-digit number + 1 = smallest 3-digit number.
Greatest 3-digit number + 1 = smallest 4-digit number.
Greatest 2-digit number + 1 = smallest 3-digit number.
Greatest 3-digit number + 1 = smallest 4-digit number.
