Find the missing number in the table given below.
| 2 | 5 | 29 |
| 4 | 3 | 25 |
| 6 | 2 | ? |
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 40
In a number table, find the rule from the complete rows and use it for the incomplete row. Here the third number is the sum of the squares of the first two:
Row 1: \(2^2+5^2=4+25=29\)
Row 2: \(4^2+3^2=16+9=25\)
Row 3: \(6^2+2^2=36+4=40\)
So the missing number is 40.
