Answer:
The general rule is 
Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between consecutive terms is always the same, and this difference is called common difference.
The general rule of an arithmetic sequence is given by:

In which
is the first term and d is the common difference.
We can also find the nth term as a function of a term m, using:

a3 = -12 and a8 = -37
First we find the common difference. So






So

Finding the first term:

Since 



So the general rule is:


In order to do this you have to substitute b with 9 and get 3a+9=54, now subtract 9 from both sides to leave a by itself and get 3a=45, now divide 3 in both sides to leave a by itself and get a=15
Hope this helps
The Question is Incomplete The complete question with figure is below.
Answer:
Therefore the equation to solve for b is

Step-by-step explanation:
Given:
In Right Angle Triangle ABC
∠C = 90°
BC = 5 cm
AB = 10 cm
∠A = 30°
To Find:
b = ?
Solution:
In Right Angle Triangle ABC Tangent identity we have

Substituting the values we get

Therefore the equation to solve for b is

Answer:
it should be 71
Step-by-step explanation:
16+5+5+5+5+5+5+5+5+5+5
+5= 71
16 is the 4th and you had 5 eleven more times becuase the numbers are increasing by 5.
