# Find the next number in this sequence

I have a homework. It seems to be an easy sequence but I can't get the answer. So, What is the next element? $$2, 7, 10, 13, 23, 34,?$$

What would be the solution out of these numbers? 45 or 49 or 58 or 39

If I say that the solution must be out of these numbers, and there is only 1 correct, what would be the solution?: 45 or 49 or 58 or 39 –  Student Jan 9 '14 at 9:28
see below: there is no "unique" solution: any of those is as good as any other –  Bernd Jan 9 '14 at 9:32

I would continue with $10+13+23+4=50$. –  Phira Jan 9 '14 at 17:26
