Answer:
see explanation
Step-by-step explanation:
(1)
The common ratio r of a geometric sequence is
r = = , so
= ( cross- multiply )
(x + 1)² = x(x - 1) ← expand both sides
x² + 2x + 1 = x² - x ( subtract x² - x from both sides )
3x + 1 = 0 ( subtract 1 from both sides )
3x = - 1 ( divide both sides by 3 )
x = -
(2)
r = = = = -
(3)
If - 1 < r < 1 then the sequence will converge
r = - meets this criteria , thus the sequence is convergent
Answer:
x - (x divided by 4). -use bidmas brackets first-
25% of x - x.
25% of x = x divided by 4
Then you would take the x divided by 4 answer and take it away from the original x.
Hope that helps. x

Answer: sometimes
Step-by-step explanation: Three points are <em>sometimes</em> collinear.
In the diagram shown, points B, G, and A are collinear
because these points all lie on the same line.
However, let's look at points A, B, and D.
Since points A, B, and D do not all lie
on the same line, they aren't collinear.
So we know that three points can sometimes be collinear.
