The age of the oldest sibling is 15 years old.

What is consecutive number?

Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers.

Here, let the age of youngest sibling be x years

              the age of middle sibling be (x+1) years

              the age of oldest sibling be (x+2) years

According to question,

        x + (x+1) + (x+2) = 42

          3x + 3 = 42

           3x = 39

             x = 13

Thus, the age of the oldest sibling is (x+ 2) years = 15 years old.
