Answer:
a_n = 2.2 + 0.6 n
a_50 = 32.2
Step-by-step explanation:
What's the common difference of this series?


Common difference =
.
Expression for the nth term:

n = 50 for the fiftieth term. Therefore
.
Infinitely many, because if you simplified the right side, it would equal the left side.

Step-by-step explanation:
you"ll have to take my word for it
At a rate of 78 ounce of water per hour, it would take 23,424 hours to drain the pond.
<h3>How long will it take to drain the pond?</h3>
First of all, we would use an appropriate conversion factor to convert the given units of water to the same unit. Thus, we would convert the unit of the pond's volume to ounce as follows:
Conversion factor:
1 gallon = 128 ounce.
14,274 gallons = X ounce
Cross-multiplying, we have:
X = 14,274 × 128
X = 1,827,072 ounces.
Now, we can calculate the time:
Rate = volume/time
Time = volume/rate
Time = 1,827,072/78
Time = 23,424 hours.
