A:
----------------------------------------------- Define x : ----------------------------------------------- Let the smallest number be x. The other two numbers will be x+1 and x+2.
----------------------------------------------- Construct equation : ----------------------------------------------- The sum of all 3 numbers is 78 ⇒ x + x + 1 + x + 2 = 78
----------------------------------------------- Solve x : ----------------------------------------------- x + x + 1 + x + 2 = 78 3x + 3 = 78 3x = 78 - 3 3x = 75 x = 25
