Answer:
37 years old
Step-by-step explanation:
If we let n represent the first number, then n + 1 is the next consecutive whole number, and n + 2 is the third number in the sequence. n + (n + 1) + (n + 2) = 3n + 3. If we solve the equation 3n + 3 = 111, we find that n = 36. Therefore, Mark is 36 years old, Taylor is 37 years old, and Brian is 38 years old.
