Re: Find the next 4 number
Hi,
The next 4 numbers should be 530865, 6419754, 75308643, 864197532 These are the Unique Numbers which comes like this, 0, 9, 198, 3087, 41976, 530865, 6419754, 75308643, 864197532 Is this the same sequence as u have asked for ? *** Innila *** |

Dont even think that i have identified this... I remember these 2 values 3087, 41976 are some kind of sequences, so thought of searching & identified the following numbers in the following link, http://www.research.att.com/~njas/sequences/A019566 I thought of giving this in the my previous post itself, but wanted to know whether it is right. *** Innila *** |

Re: Find the next 4 number
Hi gsnphani,
The constant Un that results if a number An consisting of n consecutive digits, in ascending order, is subtracted from the number An' obtained by reversing the digits of An. For example, a three-digit number 345, if subtracted from its reverse 543, yields a difference of 198. Any other three-digit number subtracted from its reverse gives the same difference. Thus U3 = 198. Similarly for a number with four consecutive digits, the unique number U4 = 3087. The first ten unique numbers are: U1 = 0, U2 = 9, U3 = 198, U4 = 3087, U5 = 41976, U6 = 530865, U7 = 6419754, U8 = 75308643, U9 = 864197532, and U10 = 9753086421. Guess u have understood the logic of unique numbers. If u still have doubts, check out the link (already given by Manoj) for more detailed explanation, http://www.shyamsundergupta.com/unique.htm Have Fun :-) *** Innila *** |
