Answer: Required expression :
Smallest number = 27
Step-by-step explanation:
Let the three consecutive number be n-1 , n , n+1 .
Since , the sum of three consecutive numbers is 84.
Remove parenthesis
Simplify
Divide both sides by 3, we get
That means the three consecutive numbers would be (28-1) , 28 , (28+1)
i.e. 27 , 28 , 29.
Hence, the smallest number is 27.
