Answer:
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 ![\frac{x+2}{x-4} = a](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B2%7D%7Bx-4%7D%20%3D%20a)
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 , ...
