Study the given pattern carefully and select the option that can replace the question mark (?).
| 3 | 7 | 6 |
| 8 | 16 | 14 |
| 18 | ? | 30 |
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 34
The pattern runs down each column: every number is twice the number above it, plus 2. The first and third columns, which are complete, show the rule.
First column: \(3\times2+2=8\), \(8\times2+2=18\)
Third column: \(6\times2+2=14\), \(14\times2+2=30\)
Second column: \(7\times2+2=16\), then \(16\times2+2=34\)
