Find the sum of the infinite geometric series, if it exists.

Mathematics

So the series looks something like this:

\Sigma_{n=4}^{\infty}\frac{n-1}{16} \\\frac{1}{16}\Sigma_{n=4}^{\infty}n-1

If \lim_{n\rightarrow\infty}\neq than \Sigma{a_n} diverges. So we must apply limit infinity property:

\lim_{n\rightarrow\infty}(ax^n+\dots+bx+c)=\infty, a>0 and n is odd.

So...

\lim_{n\rightarrow\infty}n-1=\infty

The series diverges.

Hope this helps.

\large\text{Part b:}\\\\\boxed{r=\dfrac{7}{3}w-5}

Step-by-step explanation:

\text{Part a}\\\\-vp+400,\ \text{then}\ \boxed{v>-\dfrac{25}{d}}\\\\\text{if}\ d

\text{Part b}\\\\7w-3r=15\qquad\text{subtract 7w from both sides}\\\\-3r=-7w+15\qquad\text{divide both sides by (-3)}\\\\\boxed{r=\dfrac{7}{3}w-5}
