The answer is choice C
------------------------------------------------
You start off with the first term being a1 = 3
Then you add on 3 to get to 6 as the second term
The next thing to do is add on -3, which is the same as subtracting 3, to get back to 3 once more.
This pattern continues on forever. To ensure you add on either +3 or -3 to the previous term, we add on the general term 3*(-1)^n
Overall, the nth term is found by a(n) = a(n-1) + 3*(-1)^n, which is what choice C shows. I'm assuming your teacher meant to write 3(-1)^n instead of 3(-1)n
Answer:
Its A. have a good day
Step-by-step explanation:
∠n = ∠p
p - 3x = 10
5x - n = 8......> 5x - p = 8
by adding the two equations
2x = 18 , x = 9
p = 37
m∠M = 180 - (2*37) = 106°
