Math Problem Statement
Find the missing number in the grid where the first column has numbers 24, ?, and 6; the second column has numbers 52, 30, and 3; and the third column has numbers 32, 24, and 4.
Solution
The image shows a 3x3 grid with some numbers filled in and one question mark. The goal is to find the value of the missing number, marked with a question mark.
Here is the grid as extracted from the image:
\hline 24 & 52 & 32 \\ \hline ? & 30 & 24 \\ \hline 6 & 3 & 4 \\ \hline \end{array}$$ ### Observations: - The columns seem to have some pattern. - The first and third rows involve decreasing numbers from left to right. ### Solution Approach: If we look at the first column: - The numbers are: 24, ?, 6. We might expect some arithmetic progression or a multiplicative pattern. Checking the pattern between the rows: - In the first column: $$24 - ? = ? - 6$$, which implies symmetry. - Similarly, for the second column: $$52 - 30 = 22$$, suggesting a reduction by 22 from row 1 to row 2. This could suggest similar patterns for the other columns. Following this idea: - In the first column, $$24 - 6 = 18$$. To keep the pattern consistent, the middle number should also decrease by 18: $$24 - 18 = 6$$. Hence, the missing number in the middle of the first column should be **18**. Thus, the missing value is **18**. Would you like a detailed explanation of the pattern analysis or have any other questions? ### Related Questions: 1. What would happen if the grid followed a multiplicative pattern instead of a subtractive one? 2. How can arithmetic progressions be generalized to solve such grids? 3. What other number series patterns could be used for this kind of problem? 4. How can symmetry help in solving puzzles involving missing numbers? 5. Could there be any other valid pattern in this grid based on different mathematical rules? **Tip:** Always check for both additive and multiplicative patterns when dealing with number grids!Ask a new question for Free
