Final answer:
The missing number in the grid based on the given pattern is 8.
Step-by-step explanation:
The missing number in the grid based on the given pattern is 8.
The pattern in the grid is that each number in the first row is the difference between the two numbers in the same column in the second row. For example, in the first column, 1 - 10 = -9. This pattern continues for the rest of the grid, so the missing number can be found by subtracting 6 from 14, resulting in 8. A magic constant is the sum of numbers in any row, column, or diagonal of a magic square. A magic square is a square grid filled with distinct positive integers such that each cell contains a different integer and the sum of the integers in each row, column and diagonal is equal.
