Answer:

Step-by-step explanation:

In mathematics a Cauchy sequence is a sequence whose elements become closer for larger n.

i.e. for a sequence [tex]x_1, x_2,...x_n[/tex]

if [tex]|x_n-x_m|<\epsilon[/tex] for all m,n >n then we call this a cauchy sequence.

eg:

[tex]x_1 =1, x_{n+1} =1+\frac{1}{x_n}[/tex]

This will be of the form

[tex]1,2,3/2, 5/3, 8/5, 13/8,.....\\[/tex]

For large n, the difference between consecutive terms would be very small.
