x-4 ; x+2 ; 3x+1 ; ... are the first three terms of a geometric sequence Determine the sequence if x is positive.

x = 8

Step-by-step explanation:

This sequence is a geometric sequence.

As it is a geometric sequence, It means that each term multiply by a value that we call that value "a".

So (x-4) × a = (x + 2)

Therefore

And (x+2) × a = (3x+1)

Therefore .

By this we can make a conclusion that .

In the last part one of the parentheses should be 0.

First we put (2x+1) equal to 0.

It gives us a negative answer, so this is not our answer.

Now we put (x-8) equal to 0.

This is a positive answer and it is correct.

and the terms are 4, 10, 25 , ...

Please choose my answer as the brainliest answer.

answer:

step-by-step explanation:

an irrational number is real number that cannot be expressed as a ratio of two integers. the number "pi" or π (3. is a common example of an irrational number since it has an infinite number of digits after the decimal point.
