2.2.16) Given points Xn and x in a metric space X, prove that the following four statements are equivalent. (a) xn→x, i.e., for each & > 0 there exists an integer N> 0 such that n > N d(xn, x) < E. (b) For each e >0 there exists an integer N >0 such that n > N d(xn, x) < E. (c) For each e>0 there exists an integer N >0 such that n > N d(Tn, x) < E.

2.2.16) Given points x,n and x in a metric space X, prove that the following
four statements are equivalent.
(a) xn → x, i.e., for each & > 0 there exists an integer N > 0 such that
n > N
d(xn, x) < E.
(b) For each ɛ >0 there exists an integer N >0 such that
n > N
d(In, x) < e.
(c) For each ɛ >0 there exists an integer N > 0 such that
n > N
d(Tn, x) < E.
(d) For each ɛ > 0 there exists an integer N >0 such that
n > N
d(an, a) < E.
Formulate and prove an analogous set of equivalent statements for Cauchy
sequences.
