1. The problem statement, all variables and given/known data
lim.......... (1 + 1/n^2)(7/n+1)
n->infinity
3. The attempt at a solution
lim.......... (1 + 1/n^2)(7/n+1)
n->infinity
= (7/n + 1) + (7/n^3 + n^2)
bring out 7 because constant..
7lim.......... (1/n + 1) + (1/n^3 + n^2)
n->infinity
.
.
.
.
.
7lim.......... (n^2 + n + 1) / (n^3 + 2n^2 +n)
n->infinity
limit does not exist.. am i correct?
