The image you've provided appears to show a grid-based puzzle where some cells contain numbers, and one cell contains a plus sign (+). The goal of the puzzle seems to involve completing the grid or finding a missing number.

To solve this puzzle, let's analyze the grid:

1. Given Numbers:

   • Top row: 4 and 2
   • Second row: 13 in the first column
   • Third row: 16 and 16 in the first and third columns

2. Empty Cells:

   • There's an empty cell in the first row and first column marked with +.
   • There are two empty cells in the second row and third row.

3. Puzzle Type:

   • This puzzle is likely about balancing the sums either horizontally, vertically, or both. Given the repeating number 16, it suggests that each row and each column might need to sum to the same total.

Let's Solve It:

• Column 1: The first column already has 13 (row 2) and 16 (row 3). The missing number in the first row (where + is) should make the sum equal to the sum of another column. Since the third column has 16 as well, this may suggest balancing against other columns.

  • Hypothesis: The sum of each column should be consistent.

• Column 2: We have 4 in the first row. The missing number in the second row plus the sum from row 3 should equal the sum of column 1 or column 3.

• Column 3: We have 2 in the first row and 16 in the third row. To balance this with another column, consider what number would make the sum match the other columns.

Potential Solution:

Let's hypothesize that each column should sum to 29, based on the sum of the first and third columns' existing numbers.

1. Column 1:

   • $X + 13 + 16 = 29$
   • $X = 29 - 29 = 0$

   However, this doesn't fit since no zeros are used.

2. Column 2:

   • $4 + Y + Z = 29$
   • $Y + Z = 25$

   Since 16 already appears in one row, the other should be 9.

3. Column 3:

   • $2 + A + 16 = 29$
   • $A = 29 - 18 = 11$

So, the missing numbers are likely 11, 9, and 7:

• Row 1, Column 1: 7
• Row 2, Column 2: 9
• Row 2, Column 3: 11

Final Grid:

7  4  2
13 9 11
16  X 16

If we solve, $7+4+2=13$, $7 + 13 + 16 = 36$, this must be matched with other rows or columns.
