Answer:
20/n+10 = 10/n+20 n
multiply both side n,
n (20/n+10) = n(10/n+20 n)
20+10n = 10+20n^2
20+10n -20 = 10+20n^2 -20
10n = 20n^2 -10
10n - 10n = 20n^2 -10 -10n
0 = = 20n^2 -10 -10n
20n^2 -10 -10n = 0
n = 1 or n = -0.5

Answer:
42 students in total
Step-by-step explanation:
we could surmise that the question wishes to find the minimum number of students who had been in Mr. Jone's algebra class, so we let 'x' represent the original count of students in the class and we have the following inequality:
14 <= x/3
x >= 42
the class had no less than 42 students
dividing both sides by -4, we get:
this means, each term is its previous term divided by -4.
now we can construct the sequence as follows:
Answer: the last term is -1/32
