Little Sloppy calculates the average of 2006 consecutive integers from 1 to 2006. When calculating the sum of these 2006 numbers, he missed one of the numbers, but he still calculates the average according to the 2006 numbers, and the result is that the number obtained is 1 less than the number that should be obtained. What is the number that the little sloppy missed when summing up?
小马虎计算1到2006这2006个连续整数的平均数．在求这2006个数的和时，他少算了其中的一个数，但他仍按2006个数计算平均数，结果求出的数比应求得的数小1．小马虎求和时漏掉的数是多少．
