Solution
Definition: A sequence is a function whose domain is the set of natural numbers or a
subset of the natural numbers. We usually use the symbol an to represent a sequence,
where n is a natural number and an is the value of the function on n.
A sequence may be finite or infinite Therefore any funtions which doesn't have a domain is not a natural number is enough Eg;root x ., fractions [without unity in denominator], cube root of x etc.
