Given:
The set of all positive integers from 10 to 15.
To find:
The given set by using the descriptive method.
Solution:
The positive integers are 1, 2, 3, 4,... .
The positive integers from 10 to 15 are 10, 11, 12, 13, 14, 15.
So, the given set has 5 elements 10, 11, 12, 13, 14, 15.
Using the descriptive method, the given set is defined as "The set of all positive integers greater than or equal to 10 and less than or equal to 15".
Therefore, the set of all positive integers greater than or equal to 10 and less than or equal to 15.
