The 8th term of a GP is -7/32 find its common ratio if its first term is 28

Ugo [173]

<h2>Common ratio = -1/2</h2>

Step-by-step explanation:

$\text{8}^{th}$ term of a Geometric progression is given as $\dfrac{-7}{32}$ . The first term is given as $28$ .

Any general Geometric progression can be represented using the series $a,ar,ar^{2},ar^{3},ar^{4}...\text{ }ar^{n-1}$ .

The first term in such a GP is given by $a$ , common ratio by $r$ , and the $n^{th}$ term is given by $ar^{n-1}$ .

In the given GP, $a=28;t_{8}=ar^{7}=\dfrac{-7}{32}\\\\28r^{7}=\dfrac{-7}{32}\\\\r^{7}=\dfrac{-1}{128}\\\\r=\dfrac{-1}{2}$

∴ Common ratio is $\dfrac{-1}{2}$ .

Answer: 226.5 ft²

Step-by-step explanation:

I divided the image into 3 rectangles and 1 triangle.

top rectangle: length = 9, height = 4 --> A = 9 x 4 = 36

middle rectangle: length = 15, height = 7 --> A = 15 x 7 = 105

bottom rectangle: length = 18, height = 4 --> A = 18 x 4 = 72

triangle: base = 9, height = 3 --> A = (9 x 3)/2 = 13.5

Total = 226.5
