Question 1144055
<br>
The question is invalid; any next two numbers will make a valid sequence.<br>
In fact that is the case with ANY problem like this, unless the statement of the problem tells you what kind of sequence it is.<br>
However, in this problem, a PROBABLE answer can be found by splitting the given sequence up into two sequences:<br><pre>
   72,    36,    18,     ___
       2,     6,    18,      ___</pre><br>
Still, even with this apparent pattern, the "correct" answer might be something completely different.
