74 pages/hour
Step-by-step explanation:
The average rate of change is the difference in the numbers of pages divided by the difference in the numbers of hours.
At the end of 3 hours, 90 pages were read.
At he end of 5 hours, 238 pages were read.

The average rate of change is the difference in pages divided by the difference in hours.
average rate of change = (148 pages)/(2 hours) = 74 pages/hour

Given : A geometric sequence : 18, 12, 8, 16/3,…
Solution :
Each term is found by multiplying the previous term by a constant in a Geometric Sequence .
In a Geometric Sequence common ratio is denoted by r

for n = 2

⇒
⇒
for n = 3

⇒
⇒
⇒
Thus the common ratio 'r' = 2/3
Answer:
80.029
Step-by-step explanation:
(8)(10)+2+1/100+9(1/1000)
=80+2+1/100+9(1/1000)
=80+201/100+9(1/1000)
=8201/100+9(1/1000)
=8201/100+9/1000
=82019/1000
