Find xif 4; 4+2×;4+4× are in Geometric sequences​
Ray Of Light [21]

Given:

4,4+2x,4+4x are in geometric sequences​.

To find:

The value of x.

Solution:

If a, b, c are in geometric sequences​, then

\dfrac{b}{a}=\dfrac{c}{b}

b^2=ac           ...(i)

It is given that 4,4+2x,4+4x are in geometric sequences​. By using (i), we get

(4+2x)^2=(4)(4+4x)

4^2+2(4)(2x)+(2x)^2=(4)(4)+4(4x)

16+16x+4x^2=16+16x

4x^2=16+16x-16-16x

On further simplification, we get

4x^2=0

x^2=0

x=0

Therefore, the value of x is 0.

Convert the repeating decimal to an improper fraction or mixed number. Include your work in your final answer. \(3.\overline{152
Lera25 [3.4K]

Answer:

Assuming the repetitive part is 152, i.e. the original repeating decimal is

A=3.152152152....

then  

1000A=3152.152152152152....

subtract A

1000A-A=3152.152152....-3.152152152....

999A=3149

A=3149/999=3+152/999=3 152/999

Therefore

3.152152152.... = 3149/999 or 3 152/999
