I think the answer is c) 4,1 .
2d-7=11d+26
-2d-26=-2d-26
-33/9=9/9d
d= -33/9
d= - 11/3
Is this what you're asking for?
Answer:
The highest score is 32.
Step-by-step explanation:
We are given the following in the question:
The mean score of 8 players is 14.5.
Let x denote the highest score.
If x is removed, the mean of the score of the remaining 7 players is 12.
Formula for mean:

Putting values, we get:

Thus, the highest score is 32.
Answer: The sequence is geometric
Step-by-step explanation:
In an arithmetic sequence, the consecutive terms differ by a common difference and this difference is linear.
Common difference = given term - the term before it
In geometric progression, the consecutive terms differ by a common ratio this difference is exponential.
Common ratio = given term/the term before it
Looking at the given sequence,
1) d = 6 - - 2 is not equal to - 18 - 6
Therefore, it is not an arithmetic sequence
2) r = 6/- 2 = - 18/6 = - 3
Therefore, it is a geometric sequence.
Well, 1/4 of 36 is 9, so 15000*9= 13500 cartridges in all
