Find the missing number in the table given below.
| 8 | 5 | 59 |
| 5 | 7 | 18 |
| 7 | 3 | ? |
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 46
In a number table, find the rule from the complete rows and use it for the incomplete row. Here the third number is the square of the first minus the second:
Row 1: \(8^2-5=64-5=59\)
Row 2: \(5^2-7=25-7=18\)
Row 3: \(7^2-3=49-3=46\)
So the missing number is 46.
