Mathematics Optional Group UPSC 2021 - ForumIAS

Mathematics Optional Group UPSC 2021

People with mathematics optional who are aiming for CSE 2021, please join this discussion forum so we can have relevant discussions on issues specific to our optional subject. I have been trying to look for people with math optional online, but it is quite difficult as it is a sparse population. Most people have Sociology, Pub Ad., History, Geography as optional subjects. Libraries have the same problem. There is no currently active group on forum either. I tried civilsdaily habitat platform but the math group is inactive there. 


We can discuss strategies to finish syllabus, topics to choose (rarely does someone study all the 13 topics), discuss best source materials and books, ask specific math problems, discuss previous year papers, etc.

Can anyone help with this one?

I haven't revised uniform convergence yet so can't help. Just googled the question but everywhere the sequence is mentioned, not the series. Also PYQ solution by IMS as well as Made Easy seem to be wrong for this question. 

If I find out the correct answer later, I'll let you know.
