1) There are infinitely many answers.
2) The question should read, "What number could be the next in this sequence?  Justify your answer."
3) Succesive differences often create something comprehensible.

5-3 = 2
9-5 = 4
and etc.

3,5,9,15,23
Find the difference in the numbers...
3 to 5 is 2
5 to 9 is 4
9 to 15 = 6
15 to 23 = 8
As you can see, the pattern is 2,4,6,8...etc. 
Now that you know the pattern, can you find the next number ?

So basically, you have to add 10 to 23. So just do 10+23

Again, that is one possible solution.  There are infinitely many others!
