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>

The sum of the arithmetic sequence is
Definition of eo-primes or relatively primes: Two numbers are said to be co-prime or relatively prime If their HCF IS 1 Hence to prove 847 and 2160 as co-prime numbers we will find their HCF and which should be 1
New steps to find HCF will be as under
2160 = 847 x 2+ 466
847 = 466 ×1 +381
466 = 381 x 1 + 85
381 =85 x 4+ 41
85 =41 x 2+3
41 =3 x 13+ 2
3 =2 x 1+1
2 =1 x 2+0
Therefore, the HCF=1 Hence, the numbers are co-primes (relatively prime).

Answer:
The equation 
could be used to represent this situation.
Step-by-step explanation:
Given:
Azul bought 10 reams of paper at the store for a total cost of $84 the tax on the purpose was $4.
Now, to find the equation that could be used to represent this situation.
Let the cost of a ream of paper be 
Total reams of paper = 10.
The tax on the purpose = $4.
The total cost = $84.
Now, to write an equation to represent this situation:
Therefore, the equation could be used to represent this situation.
