Question 1203321
<br>
1/2, 3/4, 1, 5/4, 3/2<br>
Get a common denominator....<br>
2/4, 3/4, 4/4, 5/4, 6/4<br>
The n-th term is (n+1)/4.<br>
Note that, without any further description of the sequence, that is only a guess as to what the sequence is.  Other much more complicated patterns could produce the same sequence.<br>
So, because multiple answers are possible, this is not a good math question.<br>
