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

$$24÷2=12$$

Explanation

Step 1: Let the numbers be

$$8x\text{ and }3x$$

Step 2: Use the difference

8x−3x=20
$$5x=20\Rightarrow x=4$$

Step 3: Find the numbers

$$8x=32,$$

$$3x=12$$
