Mathematics
1 answer:
Paladinen [302]3 years ago
5 0

Answer:

Arithmetic sequence

Step-by-step explanation:

A sequence is described as an arithmetic sequence when there is a common difference between the numbers

A sequence is a geometric sequence when there is a common ratio between the numbers

12,10,8

10-12= -2

8-10= -2

10/12= 0.83

8/10= 0.8

Hence the sequence is an arithmetic sequence with a common difference of -2

Tito bought a rare album for $68.00 and later sold it for $76.00 what is the percent of increase , rounded to the nearest tenth?
Lostsunrise [7]

Answer:

Percent of increase=11.8%

Step-by-step explanation:

It is given in the question that Tito bought a rare album for $68.00 and later sold it for $76.00 .

So increase in price is the difference of selling price and the buying price. That is,

76-68=$8

And the percentage is

\frac{8}{68}*100=11.8%

And that's the required answer.

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.
