The positions are 1,2,3,4 please answer this quickly it is due soon I will mark brainiest and I will give 14 points

Step-by-step explanation:

This is Arithmetic sequence

a = first term= 4;

d= difference =second term - first term = 7 - 4 = 3

n= position

nth term = a + (n-1)*d

1st term = 4 + (1-1)*3 = 4 + 0 = 4

2nd term = 4 + (2-1)*3 = 4 + 1*3 = 4+3 = 7

5th term = 4 + (5-1)*3 = 4 + 4*3 = 4 + 12 = 16

6th term = 4 + (6-1)*3 = 4 + 5*3 = 4 + 15 = 19

or

To get the next term add the difference [3] to the previous term.

5th term = 13 +3 = 16

6th term = 16 + 3= 19

is it i think

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
