Answer:
Explanation:
Here's a step-by-step explanation to find the three consecutive numbers whose sum is 42:
Let's call the smallest of the three numbers "x".
Since they are consecutive numbers, we can represent the next two numbers as x+1 and x+2.
The sum of these three numbers can be represented as x + (x + 1) + (x + 2) = 42.
Simplifying this equation, we get 3x + 3 = 42.
Subtracting 3 from both sides, we get 3x = 39.
Dividing both sides by 3, we get x = 13.
So, the three consecutive numbers are 13, 14, and 15.
