Find the th partial sum of the telescoping series, and use it to determine whether the series converges or diverges. If it conve
wolverine [178]

Answer:

Step-by-step explanation:

1) In a telescoping series almost every term cancels either with a prior or with the subsequent term. To determine if a Series converges to a finite value or infinite value we need to calculate its partial sum.

2) So let's  start with this sum:

S=1-1+1-1+1...\sum_{n=1}^{\infty}(-1)^{n-1}\\

3) Let's sum its partial sum to find out if it converges  or diverges, i.e.:

\\\sum_{n=1}^{N}(-1)^{n-1}=1+0+1+0+1\\n=1 \:S=1\\n=2\:S=1-1=0\\n=3\:S=1-1+1=1\\n=4\:S=1-1+1-1=0\\n=5\:S=1-1+1-1+1=1

4) The value for this

\\\lim_{n\rightarrow \infty}\sum_{n=1}^{N}(-1)^{n-1}=Limit\: Does\: not\:Exist

Then this Telescoping Series is divergent, because it does not converge to a finite value.

Solve m=9/5p+18 for p.
Goshia [24]
m=\dfrac{9}{5p+18}\\\\\dfrac{9}{5p+18}=\dfrac{m}{1}\ \ \ \ \ |cross\ multiply\\\\m(5p+18)=9\\\\5mp+18m=9\ \ \ \ |subtract\ 18m\ from\ both\ sides\\\\5mp=9-18m\ \ \ \ \ \ |divide\ both\ sides\ by\ 5m\\\\\boxed{p=\frac{9-18m}{5m}}
