Don't know if it is still useful, as it is past 10 minutes.
An interval is a mathematical notation to indicate a continuous range of numbers. The lower limits and upper limits are separated by a comma. If the lower limit is included in the interval, we put an opening bracket [ before the limit, if it is excluded, we put an opening parenthesis (. Same goes for the upper limit, but the bracket/parenthesis is placed after the upper limit.
For example,
[4,8)
will range from 4 to 8, but 8 is excluded.

It is also important to specify the number space if the interval does not contain real numbers (i.e. with decimals, etc.)
