How could we construct a FA by finding out a pattern in this language if we take n is odd then we consider n=1 ,3 ,5 ,7 (here string is in AP so we would be able to find out FA) it is okay but it it not said that we should ... but now there is no pattern now how can we construct a FA ).... can someone explain this ? Assume same for if n is even.

Regarding cutoffs in IITB
The admission session has not yet started for IITB , but going through previous year's cutoff announcement on their webpage , we can make some idea. Here is the link :- http://www1.iitb.ac.in/newacadhome/Cutofffiles/DeptMtechCutoff.jsp So my question ... getting a call then that would be a waste. So can someone please clarify , when they publish their cutoff score? Thanks
