[ 1/1Inequality]
    Assignment:Find the solution set of inequality (1-0.001)^(n+1)+(n+1)*0.001*(1-0.001)^n >= 0.99 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1 - 0.001 ) ^ ( n + 1 ) + ( n + 1 ) * 0.001 * ( 1 - 0.001 ) ^ n >= 0.99         (1)

---

    From inequality(1)：
         -135.590578 ≤ n ≤ 73990667/500000

---

    The final solution set is :
         -135.590578 ≤ n ≤ 73990667/500000
