Answer is 8, 10, 12

Step by step

Looking for consecutive even numbers and using n for number

We have three unknown even numbers, so we start with “n” and add 2 to each consecutive “n”

n + (n + 2 ) + (n + 4 ) = 30
simplify

3n + 6 = 30
Subtract 6 from both sides

3n + 6 -6 = 30 - 6
Simplify

3n = 24
Divide both sides by 3 to solve for n

3/3 n = 24/3
Simplify

n = 8

So our formula says our consecutive even numbers, since n=8,

n + 2 = 10
n + 4 = 12

Check your work

8 + 10 + 12 =30
Problem solved
