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

• Quick Sort is a divide-and-conquer sorting algorithm.
• In the worst case, it occurs when the pivot divides the array very unevenly (e.g., always smallest or largest element).
• This results in O(n²) comparisons for an array of size n.

Additional information:

• Average case → O(n log n)
• Best case → O(n log n)
• Worst case → O(n²)
