What is the sum of the geometric series?

Alla [95]

Answer:

Step-by-step explanation:

The given geometric series is:

$\sum_{n=1}^4(-2)(-3)^{n-1}$ .

When n=1, $a_1=(-2)(-3)^{1-1}$ , $\implies a_1=(-2)(-3)^{0}=-2$

When n=2, $a_2=(-2)(-3)^{2-1}$ , $\implies a_2=(-2)(-3)^{1}=6$

When n=3, $a_3=(-2)(-3)^{3-1}$ , $\implies a_3=(-2)(-3)^{2}=-18$

When n=4, $a_4=(-2)(-3)^{4-1}$ , $\implies a_4=(-2)(-3)^{3}=54$

The sum of the given series is:

-2+6-18+54=40
