每注两元，中奖的话19.4，保本不赔的卖法

  var countCurrPay = function (n) {
      var orderCurr = n; //n本次是第几次购买
      var SumBefore = 0; //之前总花费
      var payCurr = 0; //本次需要花费金额
      for (var i = 1; i < orderCurr; i++) {

          if (sumCurr == 0) {
              sumCurr = 2;
          }
          if (Math.ceil(sumCurr) % 2 == 1) {
              sumCurr = Math.ceil(sumCurr) + 1;
