this equation just multiplied my depression by 2 omg im so sorry dawg .
Answer:
principle= 6000
time =9 years
rate = 7%
so,
compound interest = p((1+r/100)^t. -1)

=6000(1.84-1)
=6000*0.84
=5040
It starts becoming bigger :)
The arithmetic sequence with the given condition is determined recursively by

So we have



and so on with the general pattern

This means the 72nd term in the sequence is

so the answer is B.
