Numbers Between 15 and 21
TOTAL NUMBERS: 5
The numbers between 15 and 21, excluding both endpoints, are listed below. Useful for math problems, ranges, and number sets.
What Are the Numbers Between 15 and 21?
To find the numbers between 15 and 21 excluding the bounds, we list all whole numbers greater than 15 and less than 21. This is a common operation in mathematics, programming, and data filtering.
How to Calculate the Count of Numbers Between
The formula to calculate how many whole numbers are between two integers is:
- Inclusive:
abs(B - A) + 1 - Exclusive:
abs(B - A) - 1
So for 15 and 21 in exclusive mode, the count is: 5.
