There are 99 numbers between 100 and 200.
To find the number of integers between two given integers (excluding the given integers themselves), you subtract the smaller number from the larger number and then subtract 1.
In this case:
200 - 100 = 100
100 - 1 = 99
Therefore, there are 99 numbers between 100 and 200 (101, 102, 103,...199).
