Show that if an is Cauchy, then the sequence bn=an2 is also Cauchy; And Give an exampleof a Cauchy sequence bn= an2 nsuch that an is not Cauchy, and give reasons.
a) Show that if an, is Cauchy, then the sequence b=a² is also Cauchy; b) Give a such that an is not Cauchy, and give an example of a Cauchy sequence b = reasons.
