Answer:
The equation which can be used to find the value of numbers
(x) + (x + 1) + (x + 2) = - 21
Explanation:
Let the first no. is = x
Second number = x + 1
Third number = x + 2
The sum of three consecutive numbers = x + x + 1 + x + 2
Given that Three consecutive integers have a sum of –21.
Therefore
(x) + (x + 1) + (x + 2) = - 21
This is the equation which can be used to find the value of numbers.
