Math Problem Statement
What number completes the pattern? Note that there is a single algebraic equation (limited to the basic arithmetic operations of addition, subtraction, multiplication, and division) that repeats across all rows.
Solution
Looking at the image you provided, we can see a 3x3 grid of numbers with a missing value in the last position. The problem asks to find the missing number, and it hints that there is a consistent arithmetic operation across the rows.
Let's analyze the grid:
9 & 1 & 6 & 4 \\ 4 & 5 & 8 & 7 \\ 1 & 3 & 5 & ? \\ \end{matrix}$$ ### Approach: 1. **Check row operations**: The missing number might follow a pattern of addition, subtraction, multiplication, or division along the rows. - For the first row: $$9 - 1 + 6 = 14 - 10 = 4$$ (this works with subtraction and addition). - For the second row: $$4 + 5 - 8 = 1 + 7 = 7$$. - For the third row: $$1 + 3 - 5 = ?$$. ### Applying the same logic to the third row: $$1 + 3 - 5 = -1$$ Thus, the missing number should be **-1**. Would you like further clarification, or do you have any questions? ### Related Questions: 1. What other patterns could be applied to the grid? 2. Can this be solved using a column-based operation? 3. Are there any alternative ways to apply arithmetic across the grid? 4. What happens if we use multiplication or division instead of addition/subtraction? 5. How do different arithmetic operations affect the pattern? ### Tip: Always consider both row-wise and column-wise arithmetic when identifying patterns in number grids.Ask a new question for Free
