The answer to your question is C. 6^1/20
Here are 3 equivalent expressions that would represent the total number of pencils and pens in Karen's backpack.
1. 4p + 6
2. p+ p + p + p + 6
3. 6 + 4(p)
Each of these has four groups of p +6 represented.
Remark
The formula for this series is
t_n = n^2 - 1
Explanation
If the series ends at 288, then the highest value n can have is 17
So you would write t_n = n^2 - 1 {n| 1 ≤ n ≤17}
If you said this to someone, you would say "t_n = n squared minus 1 where n is such that 1 is greater than or equal to 1 or less than or equal to 17"
Example
What is the 4th term in this series?
t_4 = 4^2 - 1
t_4 = 16 - 1
t_4 = 15
2 miles = 3520 yards (Americans wtf)
200 yards for 1 group = 5 minutes
400 yards for 2 groups = 5 minutes
1 minutes for 2 group = 80 yards
3520 yards for 2 groups = (3520:80 or 3520:400*5) minutes
So the answer is 44 minutes.
relative minimum is -2 when x is -3
