Question

The sum of three consecutive integers is 87. what is the smallest of these integers

Answer 1

Consecutive numbers are numbers that follow one another and the difference between two numbers following each other is 1.

Let the first number be x then the second and the third number will be :

Second number = x + 1

Third number = x + 1 + 1 = x + 2

Their sum gives 87.

We write this as follows :

x + x + 1 + x + 2 = 3x + 3

3x + 3 = 87

3x = 87 - 3

3x = 84

x = 28

The smallest number is the first number and this is :

28
