You find a piece of paper in the print tray with the above characters printed. You notice that the space between the h and the i is blank. What should be placed there and why?


Read the title again.

P.S. I've used both and because I don't want to reveal what kind of a sequence it is. Will be valid here as well?

Nothing should be placed there.

It is the sequence of segments that aren't lit up when a 7-segment display goes from zero to nine. The ninth term in the sequence is nothing because all 7 segments are lit up for the digit eight.

    $\begingroup$ That looks like the right answer, but if so, then h is wrong and should have the middle segment shown. $\endgroup$
