This in = the sequence 1, 3, 5, 7, ... , the distance is 2 while in the sequence 6,= 12, 18, 24, ... , the distance is 6. Each of these problems is in two halves: a) Understanding the mathematics behind the question b) Writing the code. Which half are you halfing (oops sorry, *having*) trouble with? If (a), this isn't a programming question at all - search the web for information on the problem, as these are well-known challenges. If (b), you'll need to post your code to get any sort of useful help - we aren't mindreaders, though we do try to look that way sometimes!
