Answer

The next line in the sequence is \( 76543 \cdot 9 + 0 = 688887 \). The conjecture is correct.

Solution

To use inductive reasoning to predict the next line in the sequence of computations, we need to identify the pattern in the given sequence. The given sequence is: 1. \( 76 \cdot 9 + 4 = 67 \) 2. \( 765 \cdot 9 + 2 = 6887 \) 3. \( 7654 \cdot 9 + 1 = 68887 \) From the sequence, we can observe that the first number in each line is increasing by 1, and the second number is 9. The third number is the result of multiplying the first number by 9 and adding the second number. Using this pattern, we can predict the next line in the sequence: 4. \( 76543 \cdot 9 + 0 = 688880 \) Now, let's calculate the result of \( 76543 \cdot 9 + 0 \) to determine if our conjecture is correct. Calculate the value by following steps: - step0: Calculate: \(76543\times 9+0\) - step1: Multiply the numbers: \(688887+0\) - step2: Remove 0: \(688887\) The result of \( 76543 \cdot 9 + 0 \) is 688887. Therefore, our conjecture is correct, and the next line in the sequence should be: 4. \( 76543 \cdot 9 + 0 = 688887 \) So, the answer is A. Yes.

Let's break down the pattern! Each time we increase the digits by one to the left and decrease the value added to the product by one. So, following this trend: For the next line, we take \( 76543 \cdot 9 + 0 \). Now let’s compute it: \( 76543 \cdot 9 = 688887 \) and then add \( 0 \), so it stays \( 688887 \). Now we can see that the number does fit in the pattern as it follows with the digits of the previous line but it still shares a similar number structure after multiplication. Based on this reasoning, the conjecture is correct! Therefore, the prediction for the line should be: \( 76543 \cdot 9 + 0 = 688887 \) which means the answer is A. Yes.
