Question

The sum of four consecutive integers is -18. What is the greatest of these integers?

Answer 1

- 3

Explanation:

x - the first of consecutive integers

x+1 - the second of consecutive integers

x+2 - the third of consecutive integers

x+3 - the fourth of consecutive integers (the greatest)

x + x+1 + x+2 + x+3 = -18

4x + 6 = -18

-6 -6

4x = -24

÷4 ÷4

x = -6

+3 +3

x+3 = -3
