Introduction

Mathematics is a fascinating subject that involves problem-solving, critical thinking, and logical reasoning. In this article, we will delve into a classic mathematical puzzle that involves three consecutive even numbers. The puzzle states that the sum of these three consecutive even numbers is 72, and we need to find the largest of the three. This puzzle requires us to apply our knowledge of arithmetic operations, algebraic expressions, and logical reasoning.

Understanding Consecutive Even Numbers

Consecutive even numbers are a sequence of even numbers that follow each other in order. For example, 2, 4, 6, 8, 10, and so on. These numbers have a common difference of 2, which means that each number is 2 more than the previous number. In this puzzle, we are dealing with three consecutive even numbers, which can be represented as x, x+2, and x+4, where x is the smallest number.

Representing the Sum of Three Consecutive Even Numbers

Let's represent the sum of the three consecutive even numbers as an algebraic expression. We know that the sum of the three numbers is 72, so we can write the equation as:

x + (x+2) + (x+4) = 72

Simplifying the Algebraic Expression

To simplify the algebraic expression, we can combine like terms. We can start by combining the x terms:

3x + 6 = 72

Solving for x

Now that we have simplified the algebraic expression, we can solve for x. To do this, we can subtract 6 from both sides of the equation:

3x = 66

Next, we can divide both sides of the equation by 3:

x = 22

Finding the Largest Number

Now that we have found the value of x, we can find the largest number by adding 4 to x:

x + 4 = 22 + 4 = 26

Therefore, the largest of the three consecutive even numbers is 26.

Conclusion

In this article, we have solved a classic mathematical puzzle that involves three consecutive even numbers. We have represented the sum of the three numbers as an algebraic expression, simplified the expression, and solved for x. Finally, we have found the largest number by adding 4 to x. This puzzle requires us to apply our knowledge of arithmetic operations, algebraic expressions, and logical reasoning. We hope that this article has provided you with a better understanding of how to solve mathematical puzzles and has inspired you to explore the world of mathematics.
