Express the interval [1, 14) in words.

  at least 1 and less than 14

Step-by-step explanation:

The square bracket on the left means that 1 is included in the interval. The value will be 1 or more. The round bracket on the right means that 14 is not included in the interval. The value will be less than 14.

The values of interest are in the interval between 1 and 14, including 1, but not 14. We can describe it as "at least one but less than fourteen."
