Answer:

Step-by-step explanation:
2,3,4,7,7,7,9,9,14,17,21

3,7,7,7,9,9,17,21

This is your answer.
900.9% would be 9.009 as a percentage.
It's 900% because it's a whole number and it's .9% because of the last 9 in the number (the thousandth - 3 digits after the decimal).
Then the number must be between 18² = 324 and 19² = 361. But is that what you want to know?
