2
Step-by-step explanation:
Divide the 2nd term by the 1st to find the common ratio or n.
The answer is the option D: D)none of the above.
The explanation is shown below:
By definition, a terminating decimal must have finite numbers of digits and it must be a rational number, which means that it can be written as a simple fraction whose numerator and denominator must be integers.
Keeping the information above on mind,you have that the option A does not have finite digits, and the options B and C can't be written as a simple fraction. Therefore, the answer is the option D.
Answer:
18 days.
Step-by-step explanation:
We have been given that 12 painters paint the wall of a school in 21 days.
So the wall painted by one painter will paint the wall in

Therefore, it will take 18 days to paint the same wall by 14 painters.
