The machine can produce 22 400 copies in 7 hours.
In 7 hours 22 400 copies were produced.
In 1 hour 22 4000/ 7 would be produced.
Therefore in 21 hours (22 400 / 7) * 21 will be produced.
Solving this = 22 400 * 3.
= 67 200 copies.

Geometric Sequence
Step-by-step explanation:
1. Check the difference.
The difference between the 1st and 2nd term
The difference between the 2nd and 3rd term
The difference is not the same. Therefore, it is not an arithmetic sequence.
2. Check the ratio
The ratio between the 1st and 2nd term
The ratio between the 2nd and 3rd term
The ratio is the same. Therefore, it is a geometric sequence.
