So my friend made a comment that the problem with number patterns is that you can make them arbitrarily difficult...well, these get pretty difficult, although not too complex (i.e., the algorithms are short, but may be hard to find!).

Find the next numbers and the algorithm for the following:

Easy:

1,3,7,15,31,63,127,255,511,1023,2047

Normal:

1,2,4,13,77,702,8478,126127,2223279,45270000

Heroic:

1,5,14,24,59,92,183,217,274,389,708,801,1282,1569,1784

Legendary:

3,-1,-6,30,23,87,78,178,-1153,-1165,-3362,-3166,-3181

GAME OVER....Do you wish to continue? ;P

Easy is

(2^n)-1

Oh...to make sure no one gets confused, let me just say this has absolutely nothing to do with Halo...I just like the way they name their difficulty levels.

Wow no replies for like a month? Maybe you'd like to post the answers to this one

4095 (double + 1)

Haha...so someone dug this up...I was beginning to think it would be relegated to the ranks of the forgotten wastelands...

Not gonna post answers, though (sorry JIf )...it's a sequence puzzle so the solution is objective, not subjective, so even if I die or (less likely ;P) retire from BrainDen, someone can still figure out the correct answer....

i agree with crip on the first one...def (2^n)-1
