what is the sum of an 8th term geometric series if the first term is -11, the last term is 180,224, and the common ratio is -4
Mumz [18]

The sum of n terms is given from the first term and the common ratio by

S_{n}=a_{1}\dfrac{r^{n}-1}{r-1}

S_{8}=(-11)\dfrac{(-4)^{8}-1}{-4-1}=(-11)\dfrac{65535}{-5}\\\\=144177
