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:



The answer is 5b²/6c
Ok so you just have to simplify
15/18 = 5/6 (cause 3*5=15 and 3*6=18)
Then you do as the picture above says.
Answer:
49
Step-by-step explanation:
To find the 'c' value c=(b/2) to the second power. divide the coefficient of x by 2 and square the result.
-12x = -48
-12x/-12 = -48/-12
x = 4
hope this helps
