EDIT:
Order of operations doesn't matter in addition. So you can add them in any order.
It is 9 7/5 I did this question in school lol
Answer:
47, 40, 33, 26 are the first four terms of the sequence.
Step-by-step explanation:
Expression representing the sequence is,

where n = number of term in the sequence
For n = 1,

= 47
For n = 2,

= 47 - 7
= 40
For n = 3,
= 47 - 7(3 -1)
= 47 - 14
= 33
For n = 4,

= 47 - 21
= 26
Therefore, first four terms of the sequence are 47, 40, 33 and 26.
The sum of 18 terms is 792.
<h3>What is an Arithmetic Sequence ?</h3>
An arithmetic sequence is defined as the sequence of numbers in which the difference between two consecutive terms is same.
First Term is 10
Common Difference = 4
The partial sum of the arithmetic sequence is given by

Here a is the first term , d is the common difference

Therefore the sum of 18 terms is 792.
