Q: 4. Prove or disprove by giving a counterexample: (a) If (xn) and (Yn) are divergent sequences then…

A: A sequence is always convergent if it's limit is unique real number. A sequence is divergent if it…

Sequence and Series

A sequence is defined as a collection of things. Series is defined to sum the things one by one in the sequence.  It was invented by German mathematician Carl Friedrich Gauss.
