Logical Sequences
What are they?
Logical sequences are lists of numbers or elements organized by a pattern.
How to solve?
You need to:
Observe the numbers
Find the pattern
Apply the rule to the next term
Simple example:
Sequence:
3, 6, 12, 24, ?
🔍 Step by step:
3 → 6 (multiplied by 2)
6 → 12 (multiplied by 2)
12 → 24 (multiplied by 2)
👉 Pattern: multiply by 2
Answer:
24 × 2 = 48
✔️ Complete sequence:
3, 6, 12, 24, 48
