Diketahui sebuah deret = 6 + 24 + 60 + 120 +........
Tentukan!
a. Suku ke- 10
b. Jumlah 20 suku pertama
Kami kirim jawaban soal yang dimaksud ya...semoga bisa difahami.
Deret : 6 + 24 + 60 + 120 +........
Suku ke 1 = U1 = 1.2.3 = 6
Suku ke 2 = U2 = 2.3.4 =24
Suku ke 3 = U3 = 3.4.5 = 60
Suku ke 4 = U4 = 4.5.6 = 120, dst... Un = n(n + 1)(n + 2)
a. Suku ke- 10 = U10 = 10.11.12 = 1320
(deret tersebut di atas merupakan deret khusus, biasa disebut deret n Bilangan Balok Pertama)
b. Jumlah 20 suku pertama
Rumus jumlah n bilangan balok pertaman Bn = 1/4 (n)(n + 1)(n + 2)(n + 3)
sehingga Jumlah 20 suku pertama B20 = 1/4 (20)(21)(22)(23) = 53130
Selamat belajar ya...

‹=› -12m = 4 - 10
‹=› -12m = -6
‹=› m = -6/-12
‹=› m = 1/2
Karena m = 1/2 maka invers penjumlahan dari m adalah -1/2
