concepts
determine whether the given statement is true or false.
$20 \in \\{3, 5, 7,\dots, 21\\}$
choose the correct answer below.

\\(\bigcirc\\) false

Explanation:

Step1: Identify set elements

The set $\{3, 5, 7,..., 21\}$ contains only odd integers starting at 3, ending at 21, increasing by 2 each time.

Step2: Check if 20 is in the set

20 is an even integer, so it cannot be part of this set of odd numbers.

Answer:

False
