This is probably a very frivolous question, but if questions were asked and answered, and out of 2868 questions, 2010 were correct, how many more questions can be answered correctly before the percentage would not change?

2010/2868=.70

2010 is 70.08% of 2868.

I am not quite understanding. If more questions are answered the percentage will go up, unless we raise the number of questions there are to be answered.

I can keep answering questions, and for each question I answer correctly, the numbers change (I am now at 2900 asked, 2023 answered correctly). Since I have already missed some, it will never take me (again, I think) to 100%, but at some point, the percentage correct will have to stop, yes? Will I be able, at some point, to achieve 99%? Or will it stop sooner? Like I said, frivolous question, I just wondered. Thanks, I appreciate you taking the time to answer

How many questions are there total?
You said you're now at 2900. How many are there to answer in all?

I don't know, as I submit the answer, I am marked 'correct' or 'incorrect' and another question is given. It's this 'thing' that my sister got me into, and now I'm hooked. I've asked her, but she says she's on four thousand and some questions, and they are still coming. I realize that it must be a finite number, but I don't know it.

Will you ever get to 99%? Unlikely.
Even if there were 10,000 questions and you answered the rest all correct, that would put you at 91.23%. 10000-2900=7100 more questions. You have 2023 correct.
7100+2023=9123

9123/10000=91.23%

In order to get to 99%, you would have to answer 89,723 questions more all correct.

$\frac{2900+x}{2023+x}=.99$

x=89,723

Thank you so very much. This means I can keep answering the questions... trivia is always fun for me... and eventually see the score rise for... ever! I so appreciate it!

If you can get the next 91 questions in a row correct, you're average will rise from 70% to 71%. Good luck!
