找规律:0,4,18,48,100,0,4,18,48,100,
找规律:0,4,18,48,100,
0,4,18,48,100,

找规律:0,4,18,48,100,0,4,18,48,100,
答案是:180
它的公式是:
N的平方乘以(N-1)
1的平方是1,乘以(1-1),结果等于0
2的平方是4,乘以(2-1),结果等于4
3的平方是9,乘以(3-1),结果等于18
4的平方是16,乘以(4-1),结果等于48
5的平方是25,乘以(5-1),结果等于100
6的平方是36,乘以(6-1),结果等于180

180

(n-1)*n^2

180
求差法
0, 4, 18, 48, 100, 180
4 14 30 52 80
10 16 22 28
6 6 6

相邻两项差4,14,30,52.再次比差10,16,22>递加6,所以22后面是28,最后答案180
