-3.6,-5.4,-8.1,-12.15 arithmetic or geometric or neither.

Mathematics
1 answer:
Brums [2.3K]3 years ago

Answer:

Geometric Sequence

Step-by-step explanation:

1. Check the difference.

The difference between the 1st and 2nd term

( - 5.4) - ( - 3.6) =  - 1.8

The difference between the 2nd and 3rd term

( - 8.1) - ( - 5.4) =  - 2.7

The difference is not the same. Therefore, it is not an arithmetic sequence.

2. Check the ratio

The ratio between the 1st and 2nd term

( - 5.4) \div ( - 3.6) = 1.5

The ratio between the 2nd and 3rd term

( - 8.1) \div ( - 5.4) = 1.5

The ratio is the same. Therefore, it is a geometric sequence.

****Brainliest to best answer!!***<br> Thank u to everyone who helps!
Dmitrij [34]

Answer:

A

Step-by-step explanation:

When you read the question it says that her average speed from the library to the gym is 15 mph less than her speed from her home to the library. So x - 15 is what describes that situation.

If it is A it cannot be anything else.

B is incorrect. x - 15 is not a time. It is a rate. It can be used to develop the amount of time, but by itself it is still A.

C is incorrect. Her average speed from her house to the library is x

D is incorrect. The distance is given as the same as from her home to the library as  from the library to the gym. Both are 4
