Observe the numbers in each cell:

Step 1: Analyze the numbers in the grid. Observe the numbers in each cell: Row 1: 16, 9, 4 Row 2: 25, 16, 9 Row 3: 36, 25, ? Step 2: Find the square root of each number in the grid. Let's look at the square roots of the numbers in each row: For Row 1: sqrt(16) = 4 sqrt(9) = 3 sqrt(4) = 2 The sequence of square roots is 4, 3, 2. For Row 2: sqrt(25) = 5 sqrt(16) = 4 sqrt(9) = 3 The sequence of square roots is 5, 4, 3. Step 3: Identify the pattern. In both Row 1 and Row 2, the square roots of the numbers form a decreasing sequence by 1. The first number's square root is 1 greater than the second, and the second is 1 greater than the third. Step 4: Apply the pattern to the third row. For Row 3: sqrt(36) = 6 sqrt(25) = 5 Following the pattern, the square root of the missing number should be 1 less than 5. So, the square root of the missing number is 5 - 1 = 4. Step 5: Calculate the missing number. If the square root of the missing number is 4, then the missing number is 4^2. 4^2 = 16 Step 6: Compare with the given options. The calculated missing number is 16. The options are: a. 49 b. 25 c. 9 d. 16 The correct option is d. The final answer is d. 16 Last free one today — make it count tomorrow, or type /upgrade for unlimited.
