Choose the missing number (?) from given alternatives.
| 7 | 49 | 343 |
| 9 | 81 | 729 |
| 6 | ? | 216 |
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 36
The first two rows show the rule: in each row the second number is the square of the first and the third is its cube.
Row 1: \(7^{2}=49\), \(7^{3}=343\)
Row 2: \(9^{2}=81\), \(9^{3}=729\)
Row 3: \(6^{3}=216\) agrees with the last number, so the missing number is \(6^{2}=\) 36
