    analyze the order and rule of the following number sequence,and figure out which will be the sixth one? 2,9,28,65,126,__,.... i learn it from a TV contest this morning. is it easy or difficult? :) this is my signature for forums quoted from shog*9: I can't help but feel, somewhere deep within that withered, bitter, scheming person, there is a small child, frightened, looking a way out.

      But I'd put it as close to easy as exists, True. But in the TV contest,the candidates were only given 10 seconds to give the answer,most failed. :-O this is my signature for forums quoted from shog*9: I can't help but feel, somewhere deep within that withered, bitter, scheming person, there is a small child, frightened, looking a way out.

        Ya know, a much slicker trick would be to write the answer, but use the same color for the foreground and background...

          DONT LOOK AT PREVIOUS POST OF MINE...IT HAS ANSWER :-D I am convinced that when you posted the answer,no one had explicitly(clearly) given the answer.(Rama was just tricking us. ;P) so why you say that? this is my signature for forums quoted from shog*9: I can't help but feel, somewhere deep within that withered, bitter, scheming person, there is a small child, frightened, looking a way out.

The answer was there in my post. sorry,Rama,maybe i used wrong word "tricking". obviously,i knew you first gave the answer because i received the notification e-mail by you. i said "tricking" because shog*9 said in his post that "people often do such tricks writing answer using the same background and foreground colors" :-O this is my signature for forums quoted from shog*9: I can't help but feel, somewhere deep within that withered, bitter, scheming person, there is a small child, frightened, looking a way out.

                                  I've had a small bit of my sig that way for some time. Generally, it just contains "---" in order to cleanly separate the sig from the rest of my post in email notifications, but occasionally i'll put in something else... ;)

                                      Yeah, I failed to see it on a first attempt, came back half an hour later and spotted it straight away. Although I have scared people in the past by being about to recite powers of two (yet I can't do times tables to save my life!) -- Help me! I'm turning into a grapefruit!
