<h2>Investigating progressive numbers, <i>n</i>, which are also square.</h2><div class="info" style="cursor:help;width:200px;margin-bottom:10px;"><h3>Problem 141</h3><span style="width:300px;color:#666;">Published on Saturday, 17th February 2007, 05:00 am; Solved by 1749</span></div>
<div class="problem_content" role="problem">
<p>A positive integer, <i>n</i>, is divided by <i>d</i> and the quotient and remainder are <i>q</i> and <i>r</i> respectively. In addition <i>d</i>, <i>q</i>, and <i>r</i> are consecutive positive integer terms in a geometric sequence, but not necessarily in that order.</p>
<p>For example, 58 divided by 6 has quotient 9 and remainder 4. It can also be seen that 4, 6, 9 are consecutive terms in a geometric sequence (common ratio 3/2).<br />
We will call such numbers, <i>n</i>, progressive.</p>
<p>Some progressive numbers, such as 9 and 10404 = 102<sup>2</sup>, happen to also be perfect squares.<br /> The sum of all progressive perfect squares below one hundred thousand is 124657.</p>
<p>Find the sum of all progressive perfect squares below one trillion (10<sup>12</sup>).</p>
