Let's examine this 4 by 4 grid. We have numbers arranged in rows and columns, with two question marks that we need to find. The grid contains various numbers, and our task is to discover the pattern that governs their arrangement. Now let's examine the rows to find a pattern. Looking at the first row: 7 plus 8 plus 4 equals 19. This matches exactly! Let's check the second row: 3 plus 14 plus 5 equals 22. The pattern holds! The sum of the first three numbers in each row equals the fourth number.
