The sum of three consecutive integers is 12 more than twice the largest integer. Which of the following equations could be used to find the three integers?

• n + n + 1 + n + 2 = 2n + 2 + 12

• n + n + 2 + n + 4 = 2(n + 4) + 12

• n + n + 1 + n + 3 = 2n + 3 + 12

• n + n + 1 + n + 2 = 2(n + 2) + 12
