Find the missing number in the grid: [[7, 4, 5], [8, 7, 6], [3, 3, ?], [29, 19, 31]]

Step 1: Analyze the numbers in the grid to find a pattern. The grid is structured as follows: 7 & 4 & 5 \\ 8 & 7 & 6 \\ 3 & 3 & ? \\ 29 & 19 & 31 Let's examine the relationship between the numbers in each column. Step 2: Identify the pattern in the first column. For the first column, the numbers are 7, 8, 3, and 29. Let's try the operation: (first number × third number) + second number. (7 × 3) + 8 = 21 + 8 = 29 This matches the fourth number in the first column. Step 3: Verify the pattern with the second column. For the second column, the numbers are 4, 7, 3, and 19. Applying the same pattern: (4 × 3) + 7 = 12 + 7 = 19 This also matches the fourth number in the second column, confirming the pattern. Step 4: Apply the pattern to the third column to find the missing number. For the third column, the numbers are 5, 6, ?, and 31. Let the missing number be x. Using the established pattern: (5 × x) + 6 = 31 Step 5: Solve the equation for x. 5x + 6 = 31 Subtract 6 from both sides: 5x = 31 - 6 5x = 25 Divide by 5: x = (25)/(5) x = 5 The missing number is 5. Step 6: Compare the result with the given options. The options are: a) 3, b) 4, c) 5, d) 6. Our calculated missing number is 5, which corresponds to option c. The final answer is c) 5.
