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 .

I think it could be plane I think
Answer:
a) z=5w-3
we have w, so we multiply it by 5 to make it 5w
and then we subtract 3 to make it 5w-3
w⇒ ×5 ⇒ -3 ⇒ z
b) x⇒ +2 = x+2
Now × 7 makes it 7(x+2)
so y=7(x+2)
Answer:
A number is written in scientific notation when there is a number greater than or equal to 1 but less than 10 multiplied by a power of 10.
If we have a number greater than 10, we move the decimal point to the left until we have a number between 1 and 10. ...
