Question

A sequence is a function whose ___ is the set of natural numbers

Answer 1

Domain.

Explanation:

A sequence is defined as the number whose domain can be a set of naturak number or can be a subset of natural numbers.

We always use the symbol of sequence as
`a_(n)`, in this n is the natural number and
`a_(n)` be the value of function. It can be finite or infinite.

If the sequence is finite then we can represent it as
`[a_(1),a_(2),a_(3)]` and if the sequence is infinite then we can represent it as
`[a_(1),a_(2),a_(3)............]`.

Answer 2

Domain

A sequence is a function whose domain is a set of natural numbers or a subset of natural numbers. We usually use the symbol
`a_(n)` to represent a sequence, where n is a natural number and
`a_(n)` is the value of the function on n.
