Chapter 8.1, Problem 5E

(a)

To determine

An infinite sequence, an finite sequence.

Explanation of Solution

Given information:

Given statement

The domain consists of the first $n$ positive integers.

Calculation:

The domain consists of the first $n$ positive integers is an example of finite sequence because it consists of $n$ positive integers which is limited up to $n$ numbers.

(b)

To determine

An infinite sequence, an finite sequence.

Answer to Problem 5E

Explanation of Solution

Given information:

The domain consists of the set of positive integers.

Calculation:

The domain consists of the set of positive integers is an example of infinite sequence because it consists of all positive integers which has no limit and ends up to infinity.
