Answer:

a) Definition of sequence of real numbers: A sequence of real number is the function from set of natural number to the set of real numbers. i.e.

f: N → R

Example: [tex]S_{n}=\frac{1}{n}[/tex]

[tex]S_{n}=\frac{n}{n+1}[/tex]

b) Definition of convergent sequence: A sequence is said to be convergent if for very large value of n, function will give the finite value.

Example: [tex]S_{n}=\frac{1}{n}[/tex]

[tex]S_{n}=\frac{n}{n+1}[/tex]

c) Definition of Cauchy sequence: A sequence is said to be Cauchy Sequence if terms of sequence get arbitrary close to one another.
