7/25, 6/25, and 11/50. Looks like they are already in order, or you meant to do that...
Answer:
he had 44 books before he bought those 6
Step-by-step explanation:
If you multiply 6 times 2 it is 12, which means if you take away 12 from 100 that is 88. if you divided 88 by 2 (the same thing you did to the 6 to make it 12%) that would be 44.
we are given
geometric sequence -36, 6, -1, 1/6, ...
first term is -36

now, we can find common ratio


now, we can find nth term

now, we can plug values
and we get

now, we can find 5th term , 6th term, 7th term
fifth term:


sixth term:


seventh term:


so, next terms are
, 
,
