What are the first three terms of the Arithmetic Sequence an = 12 – 2(n – 1)? Group of answer choices

11, 10, 9

12, 10, 8

0, 10, 20

1, 2, 3

B

Step-by-step explanation:

an = 12  - 2(n - 1)

a1 = 12 - 2(0)

a1 = 12

a2 = 12 - 2(2 - 1)

a2 = 12 - 2

a2 = 10

a3 = 12 - 2(3-1)

a3 = 12 - 2*2

a3 = 8

I think B must be the correct answer. I don't think you can start with n = 0 but the question should qualify that.

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
