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.

you should try to construct example on your own that will help you. Take an = 2-(3/n) converges to 2 here m=1
sir here Xn will be -1 ,1/2 ,1, 5/4........
here Xn is -1 which is not greater than 0
but in theorem Xn is greater than 0
It says xn > 0 for all n>m
after some natural no m , Xn should be greater than zero.
ok sir
