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

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

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

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

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

I will give brainiest to whoever answers correctly !!

NemiM [27]

Step-by-step explanation:

A) In order to calculate the interest , we can use the following formula :

$P=P_{0}.(1+i)^{t}$

Where P is the interest , P0 is the initial value, i is the interest and t is the time.

So , using P0 =600,i= 0.0005768 and t=27 ,we have :

$P=600.(1+0.0005768)^{27} \\P=600.(1.01569)\\P=609.41$

Calculating only the interest, we have :

$I=609.41-600\\I=9.41\\$

So the interest is $9.41.

B) He paid the final value calculated above, that is , $609.41.
