1,8,81,1024...
1^2 2^3 3^4 4^5 5^6 6^7...
1,8,81,1024,15625,279936
n^(n+1)

1,4,27,256...
1^1 2^2 3^3 4^4 5^5 6^6

1. 不懂了

2. =1^1, 2^2 , 3^3, 4^4, 5^5, 6^6
式=n^n
= 1,4,27,256,3125,46656

3. 黎個你有冇抄錯....如果182係之後兩個就會岩...
=1*2, 3*4, 5*6, 7*8, 9*10, 11*12, 13*14
式=(2n-1)(2n)
=2, 12, 30, 56, 90, 132, 182

4. =1^2 , 2^3, 3^4, 4^5, 5^6, 6^7
式=n^(n+1)
=1,8,81,1024, 15625, 279936
