Largest Even Numbers Summing Under 216: A Step-by-Step Solution
Hey guys! Ever get those math problems that seem like a puzzle? Today, we're diving into one that involves even numbers, consecutive sequences, and a little bit of inequality. It’s like a mini-detective game with numbers, and we're here to crack the case together. So, let’s get started and unravel this numerical mystery!
The Challenge: Sum of Three Consecutive Even Numbers
The problem throws us a curveball: “The sum of three consecutive even numbers is less than 216. What are the largest possible values for such numbers?” Sounds like a mouthful, right? But don't worry, we're going to break it down step by step.
First, let's decode the key phrases. "Consecutive even numbers" means even numbers that follow each other in order, like 2, 4, 6, or 10, 12, 14. The difference between each number is always 2. The phrase "less than 216" tells us that the total of our three numbers has to be smaller than 216, but not equal to it. Our mission is to find the largest possible even numbers that fit this rule. Think of it as finding the biggest pieces of a puzzle that still fit within the frame.
To make things easier, we can use a little algebra. Let's call the first even number "x". Since the next even number is always 2 more than the previous one, the second number will be "x + 2", and the third will be "x + 4". Now we can express the problem as an inequality: x + (x + 2) + (x + 4) < 216. This inequality is the key to unlocking our solution. We've translated the words into a mathematical statement that we can work with. It's like turning a riddle into a set of instructions.
Now, let’s dive deeper into solving this inequality. We need to simplify it, isolate "x", and figure out the range of possible values. Once we know what "x" can be, we can find our three mystery numbers. It's all about putting the pieces together in the right way, and we're about to do just that!
Solving the Inequality: Unlocking the Numbers
Okay, let's get our hands dirty with the math. We've got the inequality: x + (x + 2) + (x + 4) < 216. The first step is to simplify it by combining like terms. We have three "x" terms, so x + x + x becomes 3x. Then we have the constants 2 and 4, which add up to 6. So, our simplified inequality looks like this: 3x + 6 < 216. See? We're already making progress!
Now, we want to isolate "x" on one side of the inequality. To do this, we need to get rid of the +6. The opposite of adding 6 is subtracting 6, so we subtract 6 from both sides of the inequality. This keeps the balance and gives us: 3x < 210. We're getting closer to the solution – it's like we're zeroing in on the target.
Next up, we need to get rid of the 3 that's multiplying "x". The opposite of multiplying by 3 is dividing by 3, so we divide both sides of the inequality by 3. This gives us: x < 70. Boom! We've found a crucial piece of information. This tells us that "x", our first even number, must be less than 70. But remember, we're looking for the largest possible even numbers, so we need to think about what even number is just below 70.
The largest even number less than 70 is 68. So, our first number, "x", is 68. Now we can easily find the other two numbers. The second number is x + 2, which is 68 + 2 = 70. And the third number is x + 4, which is 68 + 4 = 72. So, our three consecutive even numbers are 68, 70, and 72. It's like we've unlocked the secret code!
But wait, we're not done yet! We need to make sure these numbers actually fit the original problem. Do they add up to less than 216? Let's check: 68 + 70 + 72 = 210. Yes! 210 is indeed less than 216. So, we've successfully found the largest possible consecutive even numbers that meet the condition. High five!
Putting It All Together: The Solution and Beyond
Alright, let's recap what we've done. We started with the problem: the sum of three consecutive even numbers is less than 216. We needed to find the largest possible values for these numbers. We translated the problem into an algebraic inequality, 3x + 6 < 216, and then we solved it step by step.
We found that the first number, "x", must be less than 70. This led us to the largest possible value for "x", which is 68. From there, we easily found the other two numbers: 70 and 72. We verified that these numbers meet the condition, and voilà , we have our solution: 68, 70, and 72. It’s like completing a puzzle and seeing the whole picture come together.
So, the largest possible values for the three consecutive even numbers are 68, 70, and 72. We did it! We tackled the problem, step by step, and emerged victorious. Give yourself a pat on the back – you've earned it!
But the fun doesn't have to stop here. This type of problem is a great way to sharpen your math skills and your problem-solving abilities. You can try changing the numbers, like making the sum less than 300 or using four consecutive even numbers instead of three. The possibilities are endless! It’s like having a set of LEGOs – you can build all sorts of different things.
This exercise isn't just about finding the right answer; it's about the process. It's about breaking down a problem, using algebra to represent the situation, solving the equation, and then checking your answer. These are valuable skills that you can use in all sorts of situations, not just in math class. It's like learning to ride a bike – once you've got it, you've got it for life.
In conclusion, we've successfully navigated the world of consecutive even numbers and inequalities. We've found the largest possible numbers that fit the criteria, and we've learned some valuable problem-solving techniques along the way. Keep practicing, keep exploring, and keep challenging yourself. Math can be a fun and rewarding adventure, and you're well on your way to becoming a math whiz!
