      Solution

      ATQ,

      Observe the pattern:

      320 → 160 → 80 → 50 → 20 → 10

      Check step-by-step:

      320 ÷ 2 = 160 ✅

      160 ÷ 2 = 80 ✅

      80 ÷ 2 = 40 ❌, but we have 50 ❌

      So 50 is incorrect.

      Then:

      Correct sequence:

      320 → 160 → 80 → 40 → 20 → 10

      ✅ Wrong number: 50

      ✅ Correct number: 40
