Answer 1

@mathstudent55

Answer 2

\[\sum_{i=1}^n i=\frac{n(n+1)}{2}\]

Answer 3

what is that @sirm3d

Answer 4

@electrokid could you please explain how to find the lim

Answer 5

\[\sum_{n=1}^n\left(\frac{14i}{n}\cdot\frac{6}{n}\right)=\frac{84}{n^2}\sum_{n=1}^n i\]

Answer 6

the answer is not 84 you are confusing me. @sirm3d

Answer 7

i did not say 84 is the answer. i am showing partial solution

Answer 8

\[\frac{84}{n^2}\sum_{n=1}^n i=\frac{84}{n^2}\cdot\frac{n(n+1)}{2}\]
now evaluate the lim at infinity of the right hand side of the equation
