Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Refer attached (Not correct way to solve. First of all we have to check whether sequence is convergent or not .If convergent then we should find limit in that way .) option d is correct
doubt
By result - Every monotonically decreasing and bounded sequence is convergent . Here an is bounded between 3/2 and 0 .
okay, please also answer the other question.
how can you be sure that the lb is 0 and not 0.7 or 1etc?
what is lower bound ? - x belongs to R is lower bound of set if all element of set is greater than or equal to x . So here -1,-2,0,-5 ...... (finite ) are all lower bounds of set .
