Introduction

In this article, we will explore the concept of consecutive odd integers and how to find their sum. We will use the given information that ${$ A + B + C = 81 $}$ to determine the value of ${$ A + C $}$.

Understanding Consecutive Odd Integers

Consecutive odd integers are a sequence of odd numbers that follow each other in order. For example, 1, 3, 5, 7, 9 are consecutive odd integers. In this case, we are given that ${$ A, B, C $}$ are consecutive odd integers such that ${$ A \ \textless \ B \ \textless \ C $}$.

Representing Consecutive Odd Integers Algebraically

Let's represent the consecutive odd integers algebraically. Since ${$ A, B, C $}$ are consecutive odd integers, we can write:

${$ A = 2n - 1 $}$
${$ B = 2n + 1 $}$
${$ C = 2n + 3 $}$

where ${$ n $}$ is an integer.

Finding the Sum of Consecutive Odd Integers

We are given that ${$ A + B + C = 81 $}$. Substituting the expressions for ${$ A, B, C $}$ in terms of ${$ n $}$, we get:

${$ (2n - 1) + (2n + 1) + (2n + 3) = 81 $}$

Simplifying the equation, we get:

${$ 6n + 3 = 81 $}$

Subtracting 3 from both sides, we get:

${$ 6n = 78 $}$

Dividing both sides by 6, we get:

${$ n = 13 $}$

Finding the Value of ${$ A + C $}$

Now that we have found the value of ${$ n $}$, we can find the value of ${$ A + C $}$. Substituting the expressions for ${$ A, C $}$ in terms of ${$ n $}$, we get:

${$ A + C = (2n - 1) + (2n + 3) $}$

Substituting ${$ n = 13 $}$, we get:

${$ A + C = (2(13) - 1) + (2(13) + 3) $}$

Simplifying the equation, we get:

${$ A + C = 25 + 29 $}$
${$ A + C = 54 $}$

Conclusion

In this article, we have explored the concept of consecutive odd integers and how to find their sum. We have used the given information that ${$ A + B + C = 81 $}$ to determine the value of ${$ A + C $}$. We have found that ${$ A + C = 54 $}$.

Final Answer

The final answer is ${$ 54 $}$.
