The common difference on the sequence is -3 and the number of books will be 21.
<h3>How to illustrate the sequence?</h3>
The formula that can be used to calculate the number of books will be:
= a + (n - 1)d
= 57 + (13 - 1)-
= 57 + (12 × -3)
= 57 - 36
= 21
Also, from the information given, each row has three fewer books than the row below it. Therefore, the common difference is -3.

Answer: 52
Step-by-step explanation:
The two angles on the base in the triangle is 17 and 111 as the angles of straight line have to be 180 so 2x = 180 - 111 - 17 as the sum of all the angles in the triangle have to be 180
x = 52
