What are the explicit equation and domain for a geometric sequence with a first term of 4 and a second term of -12

Explicit formula is:

aₙ = 4(-3)ⁿ⁻¹

The domain of the above formula is:

-∞<n<∞

Step-by-step explanation:

The explicit equation can be found by using the formula

aₙ = a₁ (r)ⁿ⁻¹

Where

a₁ is the first term and

r is the common ratio

We are given a₁ = 4 and a₂ = -12

r = -12/4 = -3

So, explicit formula is:

aₙ = 4(-3)ⁿ⁻¹

The domain of the above formula is:

-∞<n<∞

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?

u

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
