# Math Help - find limit of s(n) as n approachs infinity.

1. ## find limit of s(n) as n approachs infinity.

s(n) = $(6/n^5) * [((n^3)*(n+1)^4)/7)]$

Can someone please explain to me why the answer of this is unbounded and not 6/7 ?!?!

degree of n in the numerator is 7

degree of n in the denominator is 5

effectively, s(n) is of the order of n^2
