Answer:

Step-by-step explanation:
<u><em>The question in English is:</em></u>
From the general term, calculate the first 4 terms.
(Consider that you must assign values to the variable n)
we have

step 1
Calculate the first term
For n=1

step 2
Calculate the second term
For n=2

step 3
Calculate the third term
For n=3

step 4
Calculate the fourth term
For n=4

therefore
the first 4 terms are

Answer:
17.1 degrees
Step-by-step explanation:
This is a tangent question because angle XYZ is adjacent to 13 and opposite of 4. This means that we will have to use opposite/adjacent. This is very simple if you know the formula. Just plug those numbers in to get 4/13 = 0.3076923076923077. However, now we need to find it in degrees. If you have an inverse calculator near you, you would plug it in to get about 17.10, which rounds to 17.1.
The correct answer for this would be -10
Infinite they’re all multiples, so they are the same line
