Explanation

Solution: (3, k, 2, 8, m, 3) এই সংখ্যাগুলোর গড় 4. যদি K ও m পূর্ণ সংখ্যা হয় এবং k

\ne

m হয় তবে সংখ্যাগুলোর মধ্যক কত ? 6 টি সংখ্যার সমষ্টি = 3 + k + 2 + 8 + m + 3 => 6

\times

4 = m + k + 16 => 24 = m + k + 16 m + k = 8 এখন, m = 7 এবং k = 1 হলে m + k = 7 + 1 = 8 হয় । এখন সংখ্যাগুলোকে ক্রমানুসারে সাজিয়ে পাই 1, 2, 3, 3, 7, 8. যেহেতু, 6টি (জোড় সংখ্যা) রয়েছে, তাই মধ্যক =

\frac{{\frac{6}{2}(\frac{6}{2} + 1)}}{2}

তম পদ দুটির সাংখিক মানের সমষ্টি = 3 তম পদ ও 4 তম পদের সমষ্টি / 2 = 3 + 3/ 2 = 6/2 = 3
