The sum of three consecutive numbers is 84. Write and solve a math expression in terms of n for the smallest of the three numbers. Include parentheses.

 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.
