if x=0;y=-1 and n is even then also the equation is satissified.so there must be more conditions as i think.OR


there can be two cases 


 (i)if n is even


 (ii)if n is odd.

hey @ vnkt.swaroop we have to find the generalised x and y for all natural numbers n and not for specialised cases like n is even or n is odd


and for all natural numbers n the ans is correct i think


i might be wrong also but i have given my  view


hope u got it............
