The most common way to find a number between two numbers is to calculate their average, also known as the midpoint. This is done by adding the two numbers together and then dividing by two.
Here's a breakdown:
Finding the Midpoint (Average)
-
Add the two numbers together: For example, if you want to find the number between 10 and 20, you would add 10 + 20 = 30.
-
Divide the sum by two: Using the previous example, 30 / 2 = 15. Therefore, 15 is the midpoint between 10 and 20.
Formula:
Midpoint = (Number 1 + Number 2) / 2
Example:
Find the number between 5 and 15.
- Midpoint = (5 + 15) / 2
- Midpoint = 20 / 2
- Midpoint = 10
Therefore, 10 is the number between 5 and 15 (specifically, it's the midpoint).
Other Numbers Between Two Numbers
It's important to note that while the midpoint is a specific and easily calculable number between two given numbers, there are infinitely many numbers between any two distinct numbers on the number line. For example, between 10 and 20, we can find numbers like 10.5, 12.7, 18.999, and so on. The method above specifically identifies the midpoint.
