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.

let an = a for all n ∈ N. Then, for every ε > 0, we have |an − a| = 0 < ε ∀ n ≥ N := 1. EXAMPLE For a given k ∈ N, Let an = 1/n1/k for all n ∈ N.
