Question

The sum of three consecutive integer is 129

Answer 1

42 , 43 , 44

Explanation:

Let the 3 integers be x - 1 x and x + 1

Set up the equation

x - 1 + x + x + 1 = 129 Collect the like terms on the left

3x = 129 Notice the 1s cancel out. Divide by 3

3x/3 = 129/3

x = 43

x - 1 = 42

x = 43

x+1 = 44

42 + 43 + 44 = 129
