SUMMARY
The set X consists of all integers n that satisfy the inequality 2 <= |n| <= 5. This includes both positive and negative integers, specifically -5, -4, -3, -2, 2, 3, 4, and 5. The misunderstanding arises from the absolute value notation, which indicates that both positive and negative values are included in the solution set. Therefore, the correct elements of set X are: -5, -4, -3, -2, 2, 3, 4, and 5.
