2 answers:
Answer:

Step-by-step explanation:
We have been given an arithmetic sequence gas
as :53,62,71,80. We are asked to find
.
We know that an arithmetic sequence is in format
, where,
= nth term,
= 1st term of sequence,
n = Number of terms,
d = Common difference.
We have been given that 1st term of our given sequence is 53.
Now, we will find d by subtracting 71 from 80 as:





Therefore,
.
Answer:

Step-by-step explanation:
The 5th term of the arithmetic sequence is 53. We can write the equation:

The 6th term of the arithmetic sequence is 62. We can write the equation:

Subtract the first equation from the second one to get:


The first term is




The 38th term of the sequence is given by:

mutiply the first bracket by 9
(9)(a)= 9a
(9)(-b)= -9b
mutiply the second bracket by 5
(5)(2a)=10a
(5)(-2b)= -10b
9a-9b+10a-10b
9a+10a-9b-10b ( combine like terms<em>)</em>

Answer:
<h3> The first: The easiest to solve for is x in the first equation.</h3>
Step-by-step explanation:
To get x from first equation you just need to subtract 4y from both sides.
The rest of variables needs two operations to get variable - subtracting and then dividing.
