    0 kahan se yaar..i thought dividing by n would do it....i think the method is right...finite quantity/infinity is zero...to 2/3

    bcoz then u can use the definitions of standard limits..in whatever limits ive done theres a lot of chopping to do before u get to a form where u can use standard limits....i think dividing by 3^n will do it...
