For the following geometric sequence find the explicit formula. {12, -6, 3, ...}

It's geometric sequence where a_1=12, q=-\dfrac{1}{2}a

So a_n=12\cdot\left(-\dfrac{1}{2}\right)^{n-1}a

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
