The sum of three consecutive even integers is 90. What is the greatest number in the series?
Explanation
The three numbers can be represented by x, x+2, and x +4. Solve the equation: x+x+2 x 4 = 90
3x + 6 = 90
3x = 84
x = 28
The three numbers are 28, 30, 32. The question asks for the largest of these.
