If x,4x+3 and 7x+3 are geometric sequence. find the value of x
please help me

x =  

r =  

Step-by-step explanation:

In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-one number called the common ratio.

For example, the sequence 2, 6, 18, 54, ... is a geometric progression with common ratio 3. Similarly 10, 5, 2.5, 1.25, ... is a geometric sequence with common ratio 1/2.

Let's take r=ratio of the geometric sequence

in first term, x is multiplied by  

First term:                   x

Second term: 4x+3 = x

Third term:     7x+3 = x

From the last 2 equation, we have to obtain r and x values.

Second equation - First equation:

3x = x r (r - 1)

Let's state: x different from 0, so we can simplify x, obtaining:

3 = - r

0 = - r - 3

r =    (only the positive value of r counts)

so, going to second term of the sequence:

4x+3 = x => x (4 - ) = -3

x ( ) = -3  =>  x =  

hope it helps..

es una operación aritmética.

step-by-step explanation:

no se que fórmula requiera, pero te puedo decir que es adición. deberías revisar porque tema vas y ver que fórmulas puedes aplicar.
