tolong dijawab...pake cara....yang ga bisa ga usah jawab....

pertama diurutkan 19,22,23,23,24,25,25,26,26,28,29,29
cari yg ditengah 25 dan 25
kedua bilangan ditambahkan 25+25:2=25

19, 22, 23, 23, 24, 25, 25, 26, 26, 28, 29, 29

Me = X(n/2) + X(n/2 + 1)
Me = X(12/2) + X(12/2 + 1)
Me = X(6) + X(7)
Me = (25 + 25)/2
Me = 50/2
Me = 25

Maaf Kalau Salah
