Solve: Sum Of 3 Consecutive Numbers Equals 72

Hey there, math enthusiasts! Ever stumbled upon a math problem that seemed like a riddle wrapped in an enigma? Well, today, we're going to crack one of those together. We're diving deep into a classic problem: finding three consecutive numbers that add up to 72. Sounds intriguing, right? Buckle up, because we're about to embark on a mathematical adventure, breaking down this problem step-by-step, and making sure you not only understand the solution but also the why behind it. Forget rote memorization; we're all about building a solid understanding here. Let's get started!

Understanding Consecutive Numbers

Before we even think about tackling the sum of three consecutive numbers, let's make sure we're all on the same page about what "consecutive numbers" actually means. Simply put, consecutive numbers are numbers that follow each other in order, each one increasing by 1. Think of it like counting: 1, 2, 3, 4... you get the idea! These numbers are right next to each other on the number line. We can have consecutive integers (whole numbers), like -2, -1, 0, 1, 2, or even consecutive even or odd numbers. Consecutive even numbers go up by 2 each time (2, 4, 6, 8), and consecutive odd numbers do the same (1, 3, 5, 7).

Now, why is this important for our problem? Because understanding this fundamental concept is the key to unlocking the solution. When we know the numbers are consecutive, we know there's a specific relationship between them – a pattern that we can use to our advantage. Let’s say we don’t know the first number; we can call it “x”. Since the next number is consecutive, it’s simply “x + 1”. And the number after that? You guessed it: “x + 2”. This simple algebraic representation is what allows us to translate the word problem into a solvable equation. See, math isn't just about numbers; it's about relationships and patterns!

Setting Up the Equation: The Key to Unlocking the Solution

Alright, guys, this is where the magic really happens. We've understood what consecutive numbers are, and now it's time to translate our word problem – finding three consecutive numbers that add up to 72 – into a mathematical equation. This is a crucial step because an equation gives us a concrete way to represent the problem and, more importantly, to solve it. Remember our little trick from before? We said if we don't know the first number, we can call it "x". The next consecutive number is "x + 1", and the one after that is "x + 2". Now, the problem tells us that the sum of these three numbers is 72. "Sum" means we're adding them together. So, we can write our equation like this:

x + (x + 1) + (x + 2) = 72

Boom! There it is. This equation perfectly captures the essence of our problem. It says, "The first number (x), plus the second number (x + 1), plus the third number (x + 2) equals 72." Notice how we've used algebra to turn a word problem into a symbolic representation. This is the power of algebra, folks! It allows us to work with unknowns and find solutions in a systematic way. Don't be intimidated by the equation; it's just a tool. And now that we have our equation, we're well on our way to cracking the code. The next step is to simplify and solve for 'x'.

Solving for 'x': Unraveling the Mystery

Okay, team, we've got our equation: x + (x + 1) + (x + 2) = 72. Now comes the fun part – solving for 'x'! This is where we put our algebraic skills to the test. The first thing we want to do is simplify the equation. Notice we have a few 'x' terms hanging around? Let's combine them! We have one 'x', another 'x', and yet another 'x', which gives us a total of 3x. So, we can rewrite our equation as:

3x + 1 + 2 = 72

Next up, let's combine the constant terms (the numbers without 'x' attached). We have 1 + 2, which equals 3. Our equation now looks even simpler:

3x + 3 = 72

Looking good, right? Now, we want to isolate the 'x' term. To do this, we need to get rid of that '+ 3' on the left side of the equation. Remember the golden rule of algebra: what you do to one side, you must do to the other! So, let's subtract 3 from both sides:

3x + 3 - 3 = 72 - 3

This simplifies to:

3x = 69

We're almost there! We have 3x equals 69, but we want to know what just one 'x' is. To do this, we need to divide both sides of the equation by 3:

3x / 3 = 69 / 3

This gives us:

x = 23

Eureka! We've found 'x'! But hold on, we're not quite done yet. Remember, 'x' is just the first number in our sequence. We need to find the other two consecutive numbers.

Finding the Three Consecutive Numbers

Alright, detectives, we've cracked the code and found that x = 23. That's the first number in our sequence of three consecutive numbers. But remember, the problem asked us to find all three numbers. So, how do we find the other two? Easy peasy! We know that consecutive numbers follow each other, each one increasing by 1. We defined our three consecutive numbers as x, x + 1, and x + 2. We already know x is 23. So:

• The first number is x = 23
• The second number is x + 1 = 23 + 1 = 24
• The third number is x + 2 = 23 + 2 = 25

There you have it! Our three consecutive numbers are 23, 24, and 25. But wait, we're not going to just trust our calculations, are we? We're going to verify our answer. This is a crucial step in problem-solving: always check your work to make sure it makes sense.

Verifying the Solution: Does It All Add Up?

Okay, let's put our solution to the test! We found that the three consecutive numbers are 23, 24, and 25. The original problem stated that the sum of these three numbers should be 72. So, let's add them up and see if we're right:

23 + 24 + 25 = ?

If we do the math, we get:

23 + 24 + 25 = 72

Woohoo! It checks out! Our solution is correct. This step is so important because it gives us confidence that we've solved the problem accurately. It's like the final piece of the puzzle clicking into place. Always, always verify your answers, especially in math. It's the best way to catch any silly mistakes and ensure you're on the right track.
