Let's call the smallest of those numbers and say that it is an even number.

THE WAY TO WRITE THE ANSWER TO THE PROBLEM:

THE EXPLANATION (in English):
You do not need to write this.
I know I use lots of words, but I am hoping it is an understandable explanation.

Since is even, the even number that follows is .
(The number in between is which would be an odd number).
The even number that follows is .
The sum of those 3 consecutive even numbers is

When adding numbers, the commutative and associative properties tell us that we get the same result adding them in any order, grouping them in any way we want.
I did not even need to write those brackets that separate those even numbers.
I can write the sum rearranged in any order, with or without brackets.
