How can I compute the Upper and Lower limit of {Sn}, which defineded as: S1 = 0, S2m = S2m-1 /2, S2m+1 = 1/2 + Sm , directely from its expression, rather than by deduction of the terms?

(i.e., from the definition of Sn, instead of from 0, 0, 1/2, 1/4, 3/4, ....)

thks!

(I'm sorry, erm, I post this question here. I had moved it into "Precalculus Mathematics" of " Homework & Coursework Questions" .

Sorry, manager.)
