36:33 it is MCQ (Single correct) so option D will be true and C is not correct as by Bolzano Weierstrass theorem every bounded sequence of real number has a convergent subsequnce

30.20 option A is not correct , it is not monotonic but its its even odd subsequences are monotonic ,both cgs to same limit.

Sir 24:00 question mai b) kai liyai only positive term sequence kei example Laine hai, becoz it's given in question, so therefore (-1) ^n isn't a valid example. In fact the b) option will be correct as both +ve term &-ve term series converges to same limit therefore +ve term series will be convergent i.e: {Xn}-----> same L

Yes,if we choose a= -1/4 then the sequence converges to the limit -1/2 . So the statement is False for every a.

sir 31.45, lambda n is not defined for n=1, since denomenator becomes zero. so option a is correct

Sir @1:05:15 , series has sum log2 . So it means it is also convergent???? I dont think so because when you apply limit comparison test it is dgt...So it is not neccessary that sum is finite so as series convergent.... Please let me know I'm contemplating right or not ????
