It certainly had a few of us at work performing mental gymnastics. It is surprising how hard it can be for some of us to deliberately think or perceive differently. Thanks for posting it. <br /><br />I have to admit, I was a little taken aback by the posturing of some commenters and imagine it relates to either bruised egos, blind arrogance or lack of awareness of how people other than themselves think. <br /><br />I think I understand those in the latter camp in that a right brain thinker has great difficulty in perceiving the way a left brain thinker would, and vice versa.<br /><br />Similarly, I might be able to wrap my mind around the mentality of someone whose arrogance prevents them from imagining approaches other than theirs might be worthy of consideration.<br /><br />But I have great difficulty in understanding the apparent anger some posters have expressed, as if they had somehow been victimized by either the puzzle, the solution or the comments.<br /><br />Great discussion on whether this qualifies as math also. It's amazing how some reject it outright, which might explain their difficulty solving the problem, since they have difficulty in adapting their thinking. Typical authoritarian follower responses from those who like their world in a tight package, always constant and reliable, never to be interpreted as anything but their literal definition of it. Poor souls, really, as they will never discover anything new, just new ways of applying the status quo.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3360583082244632912.post-67145297554072769312011-10-15T12:53:03.136+02:002011-10-15T12:53:03.136+02:00idiots....it's so simple ...

For example 8 has 2 enclosed regions. 9 and 0 both have only 1 along with 6 and 4. If you add up the number of enclosed region per four digit "number" you arrive at the answer.<br /><br />For example 6764=3 because:<br />6 has one region<br />7 has zero regions<br />6 has one region<br />4 has one region<br />summed together there are 3 enclosed regions.<br /><br />Not mathematics other than adding.

Wha...Consider the following sequence...<br /><br />2,4,6,...<br /><br />What's next? As was stated earlier it can be anything.<br /><br />Today I choose the next number to be 73. And here is a formula that makes it so...<br /><br />(-1/3)(x-2)(x-3)(x-4) + 2(x-1)(x-3)(x-4) + (-3)(x-1)(x-2)(x-4) + (73/6)(x-1)(x-2)(x-3)<br /><br />so.. when x=1 then<br /><br />f(1)=(-1/3)(1-2)(1-3)(1-4) + 0 + 0 +0<br />f(1)=2<br /><br />and when x=2<br /><br />f(2)=0 + 2(2-1)(2-3)(2-4) + 0 + 0<br />f(2)=4<br /><br />and when x=3<br /><br />f(3)=0 + 0 + (-3)(3-1)(3-2)(3-4) + 0<br />f(3)=6<br /><br />and magically :) when x=4<br /><br />f(4)=0 + 0 + 0 + (73/6)(4-1)(4-2)(4-3)<br />f(4)=(73/6)(3)(2)(1)<br />f(4)=(73/6)(6)<br />f(4)=73<br /><br />So we simply use the idea that any product with a zero in it will always be zero. This has the nice effect of cancelling out our big ugly formula.<br /><br />A similar logic could be applied to the original sequence to make the answer anything we want it to be.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3360583082244632912.post-42071346456249314612009-09-13T19:54:50.307+02:002009-09-13T19:54:50.307+02:00Hi, Eclectic,

As you know questions such as "find the next number in the sequence" are always invalid, as a real sequence is any injection from N into R. That is a sequence is only truely determined if you provide an instructions on how to get to the next one. If this were an arbitary sequence the next number might as well be Pi, since we were not given any properties of the sequence this is a valid answer.Anonymousnoreply@blogger.com
