The Sum of Three Consecutive Even Numbers Is 54. What Is the Largest Number?

Mathematics offers elegant solutions to seemingly simple questions, and one intriguing problem involves finding three consecutive even numbers whose total is 54. Understanding how to identify these numbers and derive the largest among them not only sharpens basic arithmetic skills but also enhances problem-solving abilities. In this article, we’ll explore how to solve the equation behind this scenario and uncover the value of the largest number.

Understanding Consecutive Even Numbers

Understanding the Context

Consecutive even numbers are numbers that follow each other in sequence, increasing by 2 each time. For example, 2, 4, 6 and 10, 12, 14 are consecutive even numbers. The key characteristic is that if you take any even number, the next two even numbers are simply that number plus 2 and plus 4.

Setting Up the Equation

Let’s define the three consecutive even numbers in terms of a variable:

Let the first even number be:
x (where x is an even number)

The sum of three consecutive even numbers is 54. What is the largest number?

Key Insights

Then the next two are:
x + 2 and x + 4

The sum of these three numbers is given as 54:
x + (x + 2) + (x + 4) = 54

Solving the Equation

Combine like terms:
x + x + 2 + x + 4 = 54
3x + 6 = 54

Subtract 6 from both sides:
3x = 54 – 6
3x = 48

The sum of the first \( n \) terms is \( S_n = 3n^2 + 5n \). The \( n \)-th term \( a_n \) is given by: \[ a_n = S_n - S_{n-1} \]

Final Thoughts

Divide both sides by 3:
x = 16

So, the first even number is 16. Then:
Second number = 16 + 2 = 18
Third (largest) number = 16 + 4 = 20

Verifying the Solution

Add the numbers to confirm:
16 + 18 + 20 = 54 — Correct!
The largest number is indeed 20.

Why This Problem Matters

This question isn't just about memorizing steps—it teaches pattern recognition, algebraic thinking, and verification. Recognizing that even numbers differ by 2, setting up a linear equation, and solving it is fundamental to mastering algebra and real-world problem-solving.

Conclusion

The sum of three consecutive even numbers is 54, and the largest of these numbers is 20. Whether solving math problems in school or applying logic in everyday life, understanding these patterns builds confidence and clarity in numerical reasoning.
