There are an infinite number of these whole numbers. Thus the series goes on without bounds. Whatever very big number you can think of there is another one which is 1 greater.
Answer:

Step-by-step explanation:
Given

Required
Values of x that make it true
First: solve the inequality.

Collect Like Terms


Multiply both sides by -1

--- The inequality changes when multiplied by a negative value
So, the solution implies that the value of x is greater than 5 (i.e. 6, 7, 8..)
Hence, the set is:
