Question

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

Answer 1

Answer:

Domain

Step-by-step explanation:

We are given the definition of sequence.

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.

Answer 2

Answer:

Domain.

Step-by-step 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 $[a_{1},a_{2},a_{3}............]$.
