The question itself makes no sense. If is sequence indexed by "n" then its limit cannot involve "n". Are you sure you have copied this correctly?
if a = (a + a )/2 for all n greater or equal to 1. show that
a converges to (a + 2a )/3.
Please help me. I know that we want to show that the absolute value of a minus(a + 2a )/3 is less than epsilon but I am not sure how to get there. Please help.
Ok so am i supposed to know what the first few terms are? can somebody please help me?
