Answer :

To find the range of a set of numbers, we need to subtract the smallest number in the set from the largest number in the set.

The given set of numbers is: [tex]\(2, 5, 8, 11, 14\)[/tex].

1. Identify the smallest number in the set:
- The smallest number is [tex]\(2\)[/tex].

2. Identify the largest number in the set:
- The largest number is [tex]\(14\)[/tex].

3. Subtract the smallest number from the largest number:
[tex]\[ 14 - 2 = 12 \][/tex]

Therefore, the range of the numbers [tex]\(2, 5, 8, 11, 14\)[/tex] is [tex]\(12\)[/tex].

The correct answer is:
