<!-- wp:paragraph -->
<p>The arithmetic mean between any two numbers is simply the average of those two numbers.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>In this case, the two numbers are x - 3 and x + 3.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Therefore, the arithmetic mean between x - 3 and x + 3 is:</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>(x - 3 + x + 3) / 2</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Simplifying the equation:</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>2x / 2</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>This cancels out the 2s, leaving us with:</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>x</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>So, the arithmetic mean between x - 3 and x + 3 is simply <strong>x</strong>.</p>
