Quick Answer
Untuk menentukan rasio deret geometri, gunakan rumus \( S = \frac{a}{1 - r} \), di mana \( S \) adalah jumlah deret geometri tak terhingga, \( a \) adalah suku pertama, dan \( r \) adalah rasio. Jika \( S = 4 \) dan \( a \) tidak disebutkan, hubungan antara \( a \) dan \( r \) adalah \( a = 4 - 4r \). Rasio \( r \) harus memenuhi syarat \( |r| < 1 \).
