Please help Determine if the given sequence is geometric. If the sequence is geometric, find the common ratio. −4, −1, 1, −4,...

A. The sequence is geometric. The common ratio is. (Type an integer or a simplified fraction.)

B. The sequence is not geometric.

C. It cannot be determined whether the sequence is geometric or not

B

Step-by-step explanation:

To determine if a sequence is geometric, the terms need to have a common ratio. This means that to get from one term to the next, you need to multiply by the same number. Here's an example geometric sequence:

1) 2, 4, 8, 16, 32...

2) 4, 6, 9...

As you can see, to get from one term to the next in both of these sequences, you need to multiply by a certain number [the common ratio]. In sequence one, this number is 2. You need to multiply a term by 2 to get to the next term. In the second sequence, this number is 3/2. To find this certain number/common ratio, you can set the terms into ratios:

9/6=3/2

6/4=3/2

This ratio between the terms we get is the common ratio. Multiplying by this number will get you to the next term.

In this case [-4, -1, 1, -4...]:

The ratios produced by the terms clearly aren't the same here, so the sequence is not geometric.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
