could you also help me with (1)^(n+1)(11^(n1))/((n+7)^6(10^(n+2)) for L and where the equation editor is?

Best ResponseYou've already chosen the best response.0I don't get what you mean by where the equation editor is? Your problem : \[L=\dfrac{(1)^{n+1}*(11^{n1})}{(n+7)^6*(10^{n+2})}\] right? and what are we supposed to do?

Best ResponseYou've already chosen the best response.0Ah... I was hoping you knew... Let me dust off the Calculus part of my brain. If I recall, it's pretty straightforward. :)

Best ResponseYou've already chosen the best response.0The ratio test says that we evaluate \[L = \lim_{n \rightarrow \infty}  \frac{a_{n+1}}{a_n} \]

Best ResponseYou've already chosen the best response.0The criteria are that if L < 1 the series converges absolutely, if L > 1 the series diverges, and if L = 1, we have no clue.
