Expressing Sets Using Set Builder Notation:[ A={7,14,21,28}] Example with Multiples of 7

Question: 1. Express the set A={7,14,21,28} using set builder notation.

Description:
In this video, we explore how to express the set A={7,14,21,28} using set builder notation. We demonstrate that each element of this set is a multiple of 7 and not greater than 28, leading to the set builder form A={x:x" is a multiple of " 7" and " 0 less than x less than equal 28}. This method provides a concise way to define sets based on specific properties of their elements.
