The smallest of these numbers is 15
Explanation: Lets create let statements to solve this
Let x = First integer
Let x + 1 = Second integer
Let x + 2 = Third integer
x + x + 1 + x + 2 = 48
3x + 3 = 48
3x = 45
x = 15
Based on this, we know that the three consecutive numbers are 15, 16, 17. Since 15 is the least out the three numbers, the answer would be 25.
