Which of the following best describes the set of numbers? -1, 2, -4, 8, infinite arithmetic series finite geometric series infinite geometric series infinite alternating sequence

Infinite alternating sequence

Step-by-step explanation:

As we know that series is basically sum of sequence, so, the given set of numbers is not an infinite arithmetic series, finite geometric series and an infinite geometric series as it is just a sequence of numbers

Now, we need to check if is an infinite alternating sequence or not .

An infinite alternating sequence is basically of form

If we take

For  n=0 , we get

For n=1 , we get

For n=2 , we get

For n=3 , we get and so on

So, we get sequence as

i.e

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
