I found One Mistake in Last Term a3 value: Last Term: a3 value is 0.06752 is Correct isn't 0.06732 that's a mistake for calculation... So, Final Last Term Video Mistake is : a4=0.06732+0.0064*0.2=0.0688 is worng ❌ Correct Answer: a4=0.06752+0.0064*0.2=0.0688 is Correct ✅ Explanation are Good and Easy Understanding 👍🏻❤️
