Question

Between 4,632 and 20,000 is what number?*

Answer 1

To find the mid-way number we do this:

find the difference between the highest number and the lowest given number.
Divide the difference by 2
Add that number to the lowest number or subtract that number from the highest number.

20,000 - 4,632 = 15,362

`(15,368)/(2)` = 7,684

4,632 + 7,684 = 12,316
or (we get the same number)
20,000 - 7,684 = 12, 316

12,316 is between 4,632 and 20,000
