Lets Get started :)
The terms given are
- 8 , + 16 , - 32 , + 64
The formula for finding the sum of this geometric sequence is:
Sn =
a₁ = first term of sequence = -8
r = common ration = -2
n = term of sum we need to find = 7
Sn =
= -344There is also another way, by simply adding, but you cannot perform this when they ask for a larger terms sums
Each term are multiplied by - 2, so to find the rest of the terms, we multiply by - 2
+ 64 x - 2 = - 128
- 128 x -2 = + 256
+256 x - 2 = - 512
( - 8 ) + ( 16 ) + ( - 32 ) + ( 64 ) + ( - 128 ) + ( 256 ) + ( - 512 ) (first 7 terms)
= -344

[ Explanation ]
- Find Area Of Rectangle That Measures 18 Feet Long And 15 Feet Wide
-----------------------------------
Area = Base · Height
Base - 15
Height - 18
- Insert Numbers Into Equation
15 · 18
15 · 18 = 270
270
Side of the parallelogram :-
3/5 - 1/5 = 2/5
Height :-
2/5 is the side of rectangle n also forms the height of parallelogram.
Area = bh
= 2/5 × 2/5
= 0.16 foot square
