						Hi
I was given the following sequence by a friend of mine and I've been working on for a week with no result, can someone help:
Complete the list:
1; 21; 2221; 18221; 21288221; .........
Thx in advance
					
				 
				
						
														
					
												Certaibly this is a vexing question Cyanure.  I'm no math major but I suspect this is one of those questions that extends into infinity so there is no final answer.  But I may be wrong.
