Series:

6, 3, 12, 6, 24, ___

Step 1: Find a pattern

• 6 → 3 (÷2)
• 3 → 12 (×4)
• 12 → 6 (÷2)
• 6 → 24 (×4)

So the pattern alternates:
÷2, ×4, ÷2, ×4, ...

Step 2: Next term

$$24÷2=12$$

Largest number = $n+3=27$.

Explanation

Sequence: 2, 1, 3, 4, 7, 11, ?

Observe the pattern:

• 2 + 1 = 3
• 1 + 3 = 4
• 3 + 4 = 7
• 4 + 7 = 11
• 7 + 11 = 18
