The Sum of Three Consecutive Even Numbers Is 54: Find the Largest Number
The Sum of Three Consecutive Even Numbers Is 54: Find the Largest Number
When you encounter a math problem like “the sum of three consecutive even numbers is 54,” it may seem simple at first—but solving it step by step reveals a clear path to understanding patterns in numbers. This classic math puzzle not only sharpens reasoning but also highlights how even numbers follow a predictable pattern.
Understanding Consecutive Even Numbers
Understanding the Context
Consecutive even numbers are numbers like 2, 4, 6 or 10, 12, 14—that is, each number differs by exactly 2. Because even numbers are spaced by 2, finding three in a row whose sum equals a specific total is manageable with algebra or creative estimation.
Setting Up the Problem
Let the smallest of the three consecutive even numbers be x.
Then the next two consecutive even numbers are:
- x + 2
- x + 4
Their sum is given as 54:
x + (x + 2) + (x + 4) = 54
Key Insights
Solving the Equation
Combine like terms:
x + x + 2 + x + 4 = 54
3x + 6 = 54
Subtract 6 from both sides:
3x = 48
Divide both sides by 3:
x = 16
Finding the Three Numbers
Final Thoughts
Now that we know x = 16 (the smallest even number), we compute the other two:
- x + 2 = 18
- x + 4 = 20
Identifying the Largest Number
Among 16, 18, and 20, the largest number is 20.
Verification
Sum the three numbers:
16 + 18 + 20 = 54 ✅
Check spacing: 16, 18, 20 — each is 2 apart, confirming consecutiveness and evenness.
Conclusion
The sum of three consecutive even numbers is 54, and the largest of these numbers is 20. This problem illustrates how basic algebra and pattern recognition simplify real-world math challenges. Whether you're learning basic equations or brushing up on number sequences, understanding consecutive even numbers is a foundational math skill.
