S is the 19th letter. E is the 5th letter. A is the 1st letter. N is the 14th letter. All together that equals 39. Sean has 4 letters in his name. 39 - 4 is 35. Sean is also 29, so 35 - 29 is 6. Sean was born on the 4th of July. So 6 x 4 is 24. With all that said, my final answer is 24. If i don't win with that logic, this thing is rigged.
