The rotation of the gears in he mesh involves a circular motion
The second gear has 2 teeth
<h3>How to determine the number of teeth?</h3>
The given parameter can be represented using the following ratio:
Ratio = Teeth : Revolution
So, we have:
23 : 60 = Teeth : 5
Express as fraction
23/60 = Teeth/5
Multiply both sides by 5
Teeth = 5*23/60
Evaluate the product
Teeth = 2
Hence, the second gear has 2 teeth

B because the sum of B is 15 and it is composite because 3*5=15
Answer:
S(1) = 1
S(n) = S(n-1) + n
Where S(n) is the sum from 1 till n
And,
S(n-1) is the sum from 1 till n-1
