Hi Manoj,

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.

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,

Have Fun :-)
