There are exactly 19 numbers between 30 and 50.
Understanding "Between"
When we ask how many numbers are between two given numbers, like 30 and 50, we are typically referring to the whole numbers (integers) that are greater than the first number and less than the second number. This means we exclude the endpoints, 30 and 50, themselves.
Listing the Numbers
According to the provided reference from Brainly.in, the whole numbers situated between 30 and 50 are explicitly listed:
The whole numbers between 30 and 50 are: 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49. The smallest whole number in this range is 31.

These are all the integers that fall strictly within the range (30, 50).
Counting the Numbers
To find the total quantity, we simply count the numbers listed above. Let's count them:
- 31
- 32
- 33
- 34
- 35
- 36
- 37
- 38
- 39
- 40
- 41
- 42
- 43
- 44
- 45
- 46
- 47
- 48
- 49
There are 19 numbers in this list.
Alternatively, a simple mathematical formula for finding the count of integers between two numbers (exclusive of endpoints) is (Ending Number - Starting Number) - 1.
In this case:
(50 - 30) - 1 = 20 - 1 = 19.
This confirms our count.
Visualizing the Count
We can also see this using a simple table format to show the range:
| Starting Point | Numbers Between (Partial List) | Ending Point | Total Count |
|---|---|---|---|
| 30 | 31, 32, ..., 48, 49 | 50 | 19 |
This table illustrates the concept of numbers strictly located between the two specified endpoints.
In summary, by identifying all the whole numbers greater than 30 and less than 50 and counting them, or by using the formula, we consistently find the total to be 19.
