The average customer for a certain utility company pays $120 per month for utilities. the company plans to decrease utility bills by 3% each year for the next five years. which of the following is formed by the amount a customer will have paid for utilities at the end of the five years?

an arithmetic series
an arithmetic sequence
a geometric series
a geometric sequence

"a geometric series"

Step-by-step explanation:

A sequence is a set of numbers in order. A series is the sum/difference of that set of numbers.

An arithmetic sequence is a series of numbers in which each terms differs which the previous by a constant.

A geometric sequence is a series of numbers where there is a constant ratio between each term and number preceeding it.

Simply, you add/subtract a number to get the next in an arithmetic series & you multiply/divide a number to get the next in a geometric series.

In this problem, since 3% (a constant ratio) is  decreasing each year, it is definitely a geometric progression.

IS it a series or sequence?

They want to know total sum after 5 years, so it is a series.

Hence, the problem described is of a geometric series.

hence, the problem described is of a geometric series.

Step-by-step explanation:

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
