Answer: a_{n}=a_{n-1}-3  ,  n\geq 2

Step-by-step explanation:

a_{1} = 18

The common difference = -3

Therefore :

a_{n}=a_{n-1}-3  ,  n\geq 2

check:

when n = 2

a_{2}= a_{1}-3

a_{2}=18-3 = 15

!!!!!!!( help me solve this problem)!!!!!!!

Hi Bre,

Since lines a and b are parallel, we know that in the image:
- ∡1 ⇔ ∡5
- ∡2 ⇔ ∡6
-       ...
- ∡4 ⇔ ∡8

We're given the angle of ∡7, which is 114°.  We can see that ∡7 + ∡8 will equal to 180° (since line b is a straight line) and since ∡8 ⇔ ∡4, we can deduct that ∡7 + ∡4 = 180°.

From here, it's just imputing the information and solving.
⇒ 114° + ∡4 = 180°
⇒ ∡4 = 180° - 114°
⇒ ∡4 = 66°

-Hope this helps!
