A(n) _______ is a function whose domain is the set of positive integers.

Short answer

A sequence is a function whose domain is the set of positive integers.

Step-by-step solution

Step 1. Write the given information.

A(n) _______ is a function whose domain is the set of positive integers.

Step 2. Fill in the blanks.

A sequence is a function whose domain is the set of positive integers.

Consider the function $f\left(x\right)=\frac{1}{x}.$The function has the following set points, $(1,1),\left(2,\frac{1}{2}\right),\left(3,\frac{1}{3}\right),$and so on, which are all positive.

Therfore,

A sequence is a function whose domain is the set of positive integers.
