The general equation of a circle, with radius R and center (h, k) is:
![(x-h)^2+(y-k)^2=R^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%2B%28y-k%29%5E2%3DR%5E2)
Using the data given, the equation would be:
Answer:4
Step-by-step explanation:
Answer:
= - 2![(-4)^{n-1}](https://tex.z-dn.net/?f=%28-4%29%5E%7Bn-1%7D)
Step-by-step explanation:
The n th term ( explicit formula ) for a geometric sequence is
= a![(r)^{n-1}](https://tex.z-dn.net/?f=%28r%29%5E%7Bn-1%7D)
where a is the first term and r the common ratio
Here a = - 2 and r = 8 ÷ - 2 = - 4, thus
= - 2![(-4)^{n-1}](https://tex.z-dn.net/?f=%28-4%29%5E%7Bn-1%7D)
