The sum of the first six terms of the geometric series is -364.
A geometric series is a sequence of terms in a fixed common ratio.
Apparently, the expression "geometric progression" comes from the "geometric mean" (Euclidean term) of segments of lengths a and b: it is the length of the side c of a square whose area is equal to the area of the rectangle. a and b. May
The series given is
2 – 6 + 18 – 54 + ...
The sum of n terms of a geometric series is given by
Sn=a1 * 1 - rn/1 - r
here the first term is 2
r = -6 /2 = -3
S = 2 (1-(-3)⁶)/(1-(-3))
S = -364
Therefore the sum of the First six terms of the geometric series is -364 .

Answer:
the topmost one maybe?
Step-by-step explanation:
I'm guessing since X & Y are negative, (it's written X,Y,Z, right?)
The point would be reducing on the X&Y axes, an since Z is positive, it would increase on the Z axis
Answer:
D. is to the right of -0.9 on the horizontal number line
Step-by-step explanation:
The given inequality is
i.e. - 0.8 > - 0.9 .......... (1)
Now, when in a number line a number a is greater than another number b, then a must be placed to the right of the number b on the number line.
So, in our case - 0.8 > - 0.9 is true and - 0.8 is tot he right of - 0.9 on the horizontal number line. (Answer)
