Answer:
True
Step-by-step explanation:
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.

F(0)= -2
f(5)= 13
so
The average rate of change is 3
10,000,000,000×200,000 = 2e+15
10 times 12 equals 120.<span>
