Find the common ratio of the geometric sequence.

Kay [80]

Answer:

The common ratio is $\frac{1}{x^4}$

Step-by-step explanation:

Geometric sequence:A geometric sequence is a sequence in which the ratio of any term to the preceding term of that term is always constant.

Common ratio: The ratio of any term to the preceding term of that term.

The $n^{th}$ term of a geometric sequence is represented by $a_n=ar^{n-1}$ .

The $1^{st}$ term of the sequence = a.

The sum of first n term is

$S_n=\frac{a(1-r^n)}{1-r}$

The common ratio = r.

Given geometric sequence,

$\frac{1}{x^{10}}$ , $\frac{1}{x^{14}}$ , $\frac{1}{x^{18}}$ , $\frac{1}{x^{22}}$ ........

The common ratio is

$=\frac{\textrm{second term}}{\textrm{first term}}$

$=\frac{\frac{1}{x^{14}}}{\frac{1}{x^{10}}}$

$=\frac{x^{10}}{x^{14}}$

$=\frac{1}{x^4}$

Answer:

$(4x - 3)(5x - 8) = 20x^2 -47x + 24$

Step-by-step explanation:

Given

$(4x - 3)(5x - 8)$

Required

Identify and correct error

The error is when the inner and outer terms are multiplied. i.e.

$4x * -8 = -32x$ not 32x

$-3 * 5x = -15x$ not 15x

So, the expression is:

$(4x - 3)(5x - 8) = 20x^2 - 32x -15x + 24$

$(4x - 3)(5x - 8) = 20x^2 -47x + 24$
