#3 <= n < 8#

#[3, 8)#

When you have brackets [], that means you include that number.

When you have parentheses (), that means you do NOT include that number.

Let's let a number be #n#.

This means that #n# is greater than or equal to #3# and less than #8#.

Therefore, the inequality is:
#3 <= n < 8#

Hope this helps!
