  1. What is his initial bet (stake)?
  2. Did you mean to say "Every time he wins, he raises his stake by 1/4 of his bankroll"?

His initial bet is $1250.  Every time he wins, he calculates his total and takes 1/4 of it to bet.  So initially he has 5000, 5000 x .25 = 1250.  If he were to win, he would earn double his bet so he would have $6250.  Recalculating he would bet $1562.50.  If he loses his bet he would maintain that amount in his next bet.  He keeps at it until he is unable to make his desired bet.
