Can someone me asap i don't have much ! 50 !

The answer is : A

Step-by-step explanation:

I dont think you really care about how to do it. Also, I tried my best. I know you really need this and I really need Brainliest so lets help eachother out.

A

Step-by-step explanation:

Geometric sequences have a pattern that is exponential. Because of this, they do not have a constant rate of change using addition or subtraction. Instead, they have a constant rate through multiplication and division called a common ratio. Tank 1 is geometric because as you subtract each y value you get a different value each time. It is not a common difference. But if you divide, you find a common ratio.

Example: 249-300= -60                              240/300 = 0.8

                192-240 = -48                              192/240 = 0.8

                 etc.                                               Common ratio of 0.8

Arithmetic sequences have a pattern that is linear. Because of this, they do have a constant rate of change using addition or subtraction. This means that the same value is added or subtracted each time to get the next value. It is known as a common difference. Tank 2 is arithmetic because you subtract 40 each time to get the next volume.

Example: 260 - 300 = -40

               220 - 260 = -40

Common difference is -40.

This means that only A is correct.

D is not correct because geometric sequences do not have common differences.  

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
