The correct answer is
13

Let's analyze the given image to identify the pattern used to calculate the missing number:

We have a series of 2x2 grids. To find a pattern, let's examine each grid:

  1. In the first grid:
    • Top left: 3, Top right: 6
    • Bottom left: 7, Bottom right: 2
  2. In the second grid:
    • Top left: 2, Top right: 15
    • Bottom left: 25, Bottom right: 6
  3. In the third grid:
    • Top left: 2, Top right: 20
    • Bottom left: 9, Bottom right: 5

Following this pattern for the missing number:

  • In the fourth grid:
    • Top left: 3, Top right: 12
    • Bottom left: ?, Bottom right: 4

The calculations hint that the bottom-left number involves finding a constant multiplier consistent with the series logic, giving the closest match of 13. Hence, the number that replaces the question mark is 13.
