![]()
Jawaban:
6560
Penjelasan dengan langkah-langkah:
2, 6, 18, 54
2, 6, 18, 54a = 2
2, 6, 18, 54a = 2r = 6/2 = 3
2, 6, 18, 54a = 2r = 6/2 = 3S8 = 2(1 - 3⁸) / 1 - 3
2, 6, 18, 54a = 2r = 6/2 = 3S8 = 2(1 - 3⁸) / 1 - 3 = 2 (1 - 6561) / -2
2, 6, 18, 54a = 2r = 6/2 = 3S8 = 2(1 - 3⁸) / 1 - 3 = 2 (1 - 6561) / -2 = 2 (-6560) / -2
2, 6, 18, 54a = 2r = 6/2 = 3S8 = 2(1 - 3⁸) / 1 - 3 = 2 (1 - 6561) / -2 = 2 (-6560) / -2 = -6560 / -1
2, 6, 18, 54a = 2r = 6/2 = 3S8 = 2(1 - 3⁸) / 1 - 3 = 2 (1 - 6561) / -2 = 2 (-6560) / -2 = -6560 / -1 = 6560
