Question 696770: hi
i was asked to find:
1. the nth term for this sequence 1/2,1/4,1/6,1/8,
2.if its convergent or not?
3. and what is its limit?
what i figured out is the nth term of the sequence is 1/2n
but i'm not sure if its convergent or not?i dont know the limit?
thank you all help is appreciated?

if An is the nth term, then
An=1%2F%282n%29 where n=1,2,3,4,...
its limit: obviously as n->infinity or -infinity, An=0
and if n->0 from the right, An=infinity or 0 from the left then An=-infinity

why it is -inf in the second case?
