**Answer:**

The sum of 8 geometric sequence is 959780

**Step-by-step explanation:**

We are given

this sequence is geometric

-4 , 24 , -144

First term is -4

so,

now, we can find common ratio

we can use formula

n=8

now, we can plug values

now, we can simplify it

and we get

Answer: X = -1 and Y = 3

—————————————

X + Y = 2

X = 2 - Y

————————

Y = x + 4

Y = 2 - Y + 4

2Y = 2 + 4

2Y = 6

Y = 3

————————

X + Y = 2

X + 3 = 2

X = -1
