Find the missing number in the following figure
| 11 | 12 | 13 |
| 14 | 15 | 16 |
| 2 | 3 | 4 |
| 39 | 57 | ? |
Answer & explanation
Correct answer: option 4
Column 1; (11, 14, 2, 39),
=> 11 + (14+2) = 39
Column 2; (12, 15, 3, 57),
=> 12 + (15+3) = 57
Column 3; (13, 16, 4, ?),
=> 13 + (16+4) = 77
Thus, "77" is correct.
