[ 1/1Inequality]
    Assignment:Find the solution set of inequality 3-[（1+n）/2∧（n-1）-1/2∧（n-2）] <168 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        3 - ( ( 1 + n ) / 2 ^ ( n - 1 ) - 1 / 2 ^ ( n - 2 ) ) <168         (1)

---

    From inequality(1)：
         n < -37.863137 或  n ＞ -4.03448

---

    The final solution set is :
         n < -37.863137 或  n ＞ -4.03448
