Penjelasan dengan langkah-langkah:
karena kamu menyuruh buat jumlahin, jadi kayak gini
= 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1
= 223
128 - 64 + 32 - 16 + ...
a = 128
r = -64/128 = -1/2
Sn = (a(1 - rⁿ)) / (1 - r)
S8 = (128(1 - (-1/2)⁸) / (1 - (-1/2))
S8 = (128(1 - 1/256)) / (1 + 1/2)
S8 = (128(256/256 - 1/256)) / (2/2 + 1/2)
S8 = (128(255/256)) / (3/2)
S8 = 255/2 × 2/3
S8 = 255/3
