Re: Complete the series....

lady einstein,
Please mention the puzzle number for which you have posted the solution.
I guess the solution is to puzzle number (xxxix); if so, the solution is not correct.

Re: Complete the series....

yes i woz answering xxxix i tried to solve it non-mathematically.. the second digits of the numbers are 1,2,3&4 so i assumed the other two's wud be 5&6.. 1st 3 digits began with 6,5&6 so i guessed the next 3 as 989,is it too far fetched?

Re: Complete the series....

lady einstein,
How would you explain the sequence in the tenths place...6,5,6, ...hence 9,8,9....I am unable to accept that as a reason good enough. Nevertheless, it was a good attempt!
