Einstein's riddle - can you solve it?

[Atlblkz06]

If Sn is the summation of 9/(10^n) from n=0 to n=inf.
then
1 = the limit as n->inf of Sn

Calc 2 at it's best, convergence... lol, takes me back to sophomore year.

lol yea good time (not). Hated calculus when I took it, learned to like it later in other math classes.

So umm the limit of Sn = 0 as n-> inf. You're dividing 9 by a 10^n which explodes as n-> inf.

[man]

how does it explode, it continuously approaches 1

9/10^1 = .9 + 9/10^2 = .99 + 9/10^3 = .999 etc...
