<p>This function uses a "for loop" to incrementally generate and return all the numbers from the start value to the end value.</p>
<h2>displayNumbers</h2>
<p>In this function, an "If/Else" statement is used to identify the odd and even numbers that were generated in the previous step. The results are then inserted and displayed in a table, with even numbers in <b>BOLD</b>.</p>
