Question

Write the following set in roster form. {2, 4, 6, 8, 10}

A) {2, 4, 6, 8, 10}
B) {1, 2, 3, 4, 5}
C) {0, 2, 4, 6, 8}
D) {1, 3, 5, 7, 9}

Answer 1

The set {2, 4, 6, 8, 10} can be expressed in roster form as (Option A) {2, 4, 6, 8, 10}.

Step-by-step explanation:

Roster form is a way to represent a set by explicitly listing its elements. In this case, the set {2, 4, 6, 8, 10} is already provided in the roster form as option A. Each element in the set is separated by commas and enclosed within curly braces, conforming to the roster form notation (Option A).

Option B, {1, 2, 3, 4, 5}, includes different elements and does not match the given set. Option C, {0, 2, 4, 6, 8}, contains the correct elements but in a different order. Option D, {1, 3, 5, 7, 9}, also includes different elements that do not correspond to the given set.

In summary, the roster form for the set {2, 4, 6, 8, 10} is accurately represented by option A. Roster form provides a clear and concise way to list the elements of a set, making it a convenient notation for small, well-defined sets like the one given in the question.
