Answer:
The sum of the arithmetic sequence is
.
Step-by-step explanation:
A sequence is a set of numbers that are in order.
In an arithmetic sequence the difference between one term and the next is a constant. In other words, we just add the same value each time infinitely.
If the first term of an arithmetic sequence is
and the common difference is d, then the nth term of the sequence is given by:

For the sequence

The pattern is continued by adding -11 to the last number each time.
An arithmetic series is the sum of an arithmetic sequence. We find the sum by adding the first,
and last term,
, divide by 2 in order to get the mean of the two values and then multiply by the number of values, <em>n</em>

Answer:
I got 7%
Step-by-step explanation:
110 x .15 = 16.5
110-16.5=93.5
93.5 x .10 = 9.35
93.5 + 9.35= $102.82
Thats the discount price
110 - 102.82 + 7.18
7.18/102 = .0698
.0698 x 100 = 6.98
7%
I have this on my middle school test and it's my first time doing it so yea. I hope it helps even if it's already too late.
I had to edit it beforee
First you find the greatest conman factor which is 2
then simplify and multiply 2 by (c-1)(c+4)
after factor our answer
is 2(c-1)(c+4)
