3, 6, 9 : 4, 8, 12 :: 5, 10, 15 : ______
easy Q11 of 15
Step-by-Step Solution
Step 1: Identify pattern:
Series1a = 3, 6, 9 → start = 3, diff = +3; Series1b = 4, 8, 12 → start = 4, diff = +4.Step 2: Apply rule:
The rule is start +1 and diff +1.Step 3: Compute new series:
Series2a = 5, 10, 15 → start = 5, diff = +5 → apply start +1 = 6; diff +1 = +6 → 6, 12, 18.Final Answer:
6, 12, 18 → Option AQuick Check:
Same structural rule (Start +1, Diff +1) holds ✅
Quick Trick: When both sequences are arithmetic, compare the first term and difference.
Common Mistakes:
- Confusing common difference with a multiplication rule.
