ANSWER
C. 35
EXPLANATION
The given expression is:
[tex]15 - 35 - \frac{85}{n} + 55 + \frac{75}{2n} + \frac{15}{2 {n}^{2} } [/tex]
As
[tex]n \to \: \infty [/tex]
[tex] \frac{k}{n} \to0[/tex]
where k is a constant.
This implies that,
[tex]15 - 35 - \frac{85}{n} + 55 + \frac{75}{2n} + \frac{15}{2 {n}^{2} } = 15 - 35 - 0 + 55 + 0+ 0 =35[/tex]
The correct answer is C
