0 Guest Posted July 19, 2010 Report Share Posted July 19, 2010 visual remove the 2 next to the six and reverse it remove the 4 next to the six and reverse it remove the 7 next to the six and reverse it therefore: 68 next remove the 8 next to the six and reverse it and you have 6 left over or more mathematical remove the 2 and reverse remove the 4 and reverse remove the 6 and reverse therefore: 78 then next remove the 8 and reverse and you'd have the 7 left over Quote Link to comment Share on other sites More sharing options...

0 Guest Posted July 19, 2010 Report Share Posted July 19, 2010 (edited) Next number is 78. In every subsequent number the smallest single digit is removed and the sequence is reversed. Edited July 19, 2010 by mohanrao2005 Quote Link to comment Share on other sites More sharing options...

0 Guest Posted July 19, 2010 Report Share Posted July 19, 2010 As mohanrao2005 (inadvertantly?) displayed. 78. (A) Between each step, the smallest digit is removed and the sequence of digits are reversed. or (B) In each n step the 2n digit is removed and the sequence of digits are reversed. With procedure (A), the final number of the sequence would be 8. With procedure (B), the final number of the sequence would be 7. Quote Link to comment Share on other sites More sharing options...
0 Guest Posted July 19, 2010 Report Share Posted July 19, 2010 what i hope is a solution I hope it is correct, the least no. is being eliminated and the number is being reversed, so 78 is the answer Quote Link to comment Share on other sites More sharing options...
0 Guest Posted July 19, 2010 Report Share Posted July 19, 2010 (edited) What is the next number in this series 87426... 6478... 876 Just a comment in that wording can make a difference. A series is defined as the sum of the terms of a sequence (finite or infinite). I did make the assumption that sak_iko was asking for the next number of a sequence, an ordered list of elements or terms, but If what actually is sought is the next term of a series, we may all have given incorrect solutions.

0 Guest Posted July 19, 2010 Report Share Posted July 19, 2010 What is the next number in this series 87426... 6478... 876 The answer is 68 87426 changed to 6472 - thus the 4th digit was removed and the sequence flipped 6472 changed to 876 - thus the 3rd digit of the original number was removed and the sequence flipped again Logically that means the second digit from the original number gets removed and you flip the sequence again and end up with the answer above Quote Link to comment Share on other sites More sharing options...
