3 ? 4 7 121 8 6 9 5
The given sequence of numbers forms a 3x3 grid:
3 ? 4
7 12 18
6 9 5
The pattern observed relates the sum of the elements in the first row to the sum of the elements in the first column.
According to the pattern, the sum of the first row must equal the sum of the first column:
$3 + ? + 4 = 3 + 7 + 6$
Combine the known numbers:
$7 + ? = 16$
Solve for the question mark (?):
$? = 16 - 7$
$? = 9$
Therefore, the number that can replace the question mark is 9.
Study the given pattern carefully and select the number from among the given options that can replace the question mark (?) in it.
| $B_{3}$ | $E_{4}$ | $H_{7}$ |
| $K_{8}$ | $N_{9}$ | ? |
