 Hello, I'm trying to evaluate the limit of an expression when the variable goes to infinity and mathematica says: ''Running'' and doesn't evaluate it. Then I have to close the program and open it again in order for it to stop saying ''Running''.

 The symbol N is reserved. Use a different name. The following code gives an answer at once: Subscript[\[Kappa]p, 1] = \[Kappa]1 + \[Mu]1/3; Subscript[\[Kappa]p, 2] = \[Kappa]2 + \[Mu]2/3; Subscript[\[Mu]p, 1] = \[Mu]1; Subscript[\[Mu]p, 2] = \[Mu]2; Subscript[c, 1] = 1 - Subscript[c, 2]; en = 2; kp = (Sum[Subscript[c, r]/( Subscript[\[Kappa]p, r] + Subscript[\[Mu]p, 1]), {r, 1, en}])^(-1) - Subscript[\[Mu]p, 1]; kp1 = Limit[ kp, {\[Kappa]1 -> \[Infinity], \[Kappa]2 -> \[Infinity], \[Mu]1 -> 5, \[Mu]2 -> 30}, Assumptions -> Subscript[c, 2] > 1]

 I didn't use the english N, which is reserved, I used the greek N, which isn't. So, something else is creating the problem but I don't know what. Thank you anyway!
