JUmlah dari 1/3+1/6+1/12+⋯+1/192=

[tex] \frac{1}{3} + \frac{1}{6} + \frac{1}{12} + \frac{1}{24} + \frac{1}{48} + \frac{1}{96} + \frac{1}{192} \\ = \frac{64 + 32 + 16 + 8 + 4 + 2 + 1}{192} \\ = \frac{127}{192} [/tex]
Maaf Kalau Salah

Un = 1/3n
U64 = 1/3(64) = 1/192

Sn = 1/2 n(a + Un)
Sn = 1/2 x 64(1/3 + 1/3 x 64)
Sn = 32(1/3 + 1/192)
Sn = 10,83 atau 10 5/6
