while loop

Question

I believe there is an error in one of the while loop questions. The question has us fill in the blanks for the following code --

$i = 1;
while($i <= __) {
echo $i;
$i__;
}
I tested this out and the correct answer is 16 in the condition part, then of course ++.
To get a 'correct' response to the question, the user needs to input 15, which should not be correct. I am not sure if it has been asked about or answered already, but am I correct that this is false?

Answer 1

no, given you're printing out numbers from 1 to 15, the answer is 15. because it says "while($i <= _)" and
not "while ($i < _)"

Answer 2

ahhh i see now.. it was late when i was looking at it.. fatigue throws me off.
