A geometric sequence refers to a sequence where to get from one term to another you need to multiply by the same number each time. This number is called common ratio or factor. 

On the case are given the numbers 1,4,16,64 as part of the sequence.

From 1 to 4 multiply by 4
From 4 to 16 multiply by 4
From 16 to 64 multiply by 4
 
After the previous reasoning, you can conclude that the common factor or ratio of the geometric sequence is 4.

#4 math homework help needed. Thank you
liubo4ka [24]

Answer:

C. -1

Step-by-step explanation:

f(x) = 2/ (-x-1)

As we can see, f(x) is a fraction with two components: numerator (2) and denominator (-x-1).

According to the theorem, the fraction only exists when its denominator is different from 0.

So that in this situation, (-x-1) has to be different from 0

- x - 1 ≠0

=> - x≠ 1

=> x ≠ -1

So that if x = -1, (-x-1) = 0, making the fraction not exist.

So the input is not allowed is x = -1
