this is so frustrating!!! i m trying to solve this sum for the last 1 hr. i m not thinking in the right way but m beating around the bush. i m observing many things but cant prove them...grrrrrrrrr
shallow thoughts.... :( :(
they r giving me many hints and clues but mathematically i cant relate them. basics...these paper-setters know where to strike...
cant even prove it with induction. i hate it when the pink book mocks at me. but i love it anyway.... hehe
ok bye for now.
