Your answer: 6
Explanation: I pretty much drew out the problem to figure out how much wheat there would be at each time. So 1=1 2=3 3=7 4=15 and from there I realized the pattern was multiply by two and add 1 so the next would be 5=31 and then finally 6=63
About Me:     I don't like math but I do it anyways
