Select the number that will replace the question mark (?) in the table below.
| 2 | 9 | 18 |
| 5 | 4 | 20 |
| 7 | 6 | ? |
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 42
In a number table, find the rule from the complete rows and use it for the incomplete row. Here the third number in each row is the product of the first two:
Row 1: \(2\times9=18\)
Row 2: \(5\times4=20\)
Row 3: \(7\times6=42\)
So the missing number is 42.
