diketahui barisan geometri memiliki suku ke-2 dan suku ke-4 yaitu 12 dan 100 tentukan rasionya dan suku pertama​

the answer should be 3.3x

The product of 3.3 and a number 'x' is represented in algebraic notation simply as 3.3x .

The product of 3.3 and the variable x is expressed as 3.3 x . This means you simply multiply 3.3 by the value of x . For example, if x = 2 , then the product is 6.6.

Jawaban:soal:Sebuah barisan geometri memiliki suku ke-2 (U2) = 12 dan suku ke-4 (U4) = 108. Kita perlu mencari rasio (r) dan suku pertama (a). caranya:1. Menentukan Rasio (r):- Rumus suku ke-n barisan geometri: Un = a * r^(n-1)- U2 = a * r = 12- U4 = a * r³ = 108- Bagi U4 dengan U2: (a * r³) / (a * r) = 108 / 12- r² = 9- r = ±32. Menentukan Suku Pertama (a):- Jika r = 3: a * 3 = 12 => a = 4- Jika r = -3: a * (-3) = 12 => a = -4 maka, ada dua kemungkinan:- Rasio (r) = 3, Suku Pertama (a) = 4- Rasio (r) = -3, Suku Pertama (a) = -4
