✔ 最佳答案
第一項 = 1 = 1^3第二項 = 8 = 2^3
第三項 = 27 = 3^3
第四項 = 64 = 4^3
.
.
.
如此類推，通項 = n^3
所以，數列為
1 , 8 , 27 , 64 , 5^3 , 6^3 , 7^3, 8^3, 9 ^3
= 1 , 8 , 27 , 64 ,125, 216, 343 , 512 , 729

The sequence is the third power of all natural numbers (1, 2, 3, ...)
The first nine numbers are 1^3, 2^3, ..., 9^3
That is, 1, 8, 27, 64, 125, 216, 343, 512, 729.
