Which formula can be used to describe the sequence?

mafiozo [28]

Answer:

The formula that can be used to describe the given sequence is $f(x)=-4(6)^{x-1}$

Step-by-step explanation:

Given : sequence -4, −24, −144,...

We have to find the formula that can be used to describe the given sequence -4, −24, −144,...

A geometric sequence is a sequence in which each higher term is multiplied by a constant number called common ratio.

Written as a, ar , ar², ar³., ....

and general term is calculated as $a_n=ar^{n-1}$

Where a is first term and r is common ratio.

Consider the given sequence -4, −24, −144,...

We find the common ratio ,

$a=-4, \\\\ar=-24,\\\\\ ar^2=-144$

Thus, common ratio is given as $r=\frac{ar}{r}=\frac{-24}{-4}=6$

Thus, the given sequence is a geometric sequence.

The general term is given by $a_n=ar^{n-1}$

Put a = -4 , r = 6

We have

$a_n=-4(6)^{n-1}$

Thus, the formula that can be used to describe the given sequence is $f(x)=-4(6)^{x-1}$

I already solve this question first I got x=26 and x=21.8 I want to know what is the answer

katovenus [111]

Answer:

$\large\boxed{\sf x = 26}$

Step-by-step explanation:

A right angled triangle is given to us and we need to find out the value of x . We may use Pythagoras Theorem here as ,

$\longrightarrow hypotenuse^2=perpendicular ^2+base^2 \\$

Here ,

perpendicular = 24
hypotenuse = x
base = 10

On substituting the respective values , we have ;

$\longrightarrow x^2 = 24^2+10^2 \\$

Solve the square ,

$\longrightarrow x^2 = 576+100\\$

Add ,

$\longrightarrow x^2 = 676 \\$

Put squareroot on both the sides ,

$\longrightarrow x =\sqrt{676} \\$

Simplify ,

$\longrightarrow \underline{\underline{ x =26}} \\$
