1乘以2乘以3乘以4加1等于5的平方
2乘以3乘以4乘以5加1等于11的平方
3乘以4乘以5乘以6加1等于19的平方
。。。。。。
（1)请写出一个普遍性的结论，并给出证明
（2)根据1，计算2007乘以2008乘以2009乘以2010加1的结果（用一个最简式子表示)
（3)写出他的第n行的一般式并证明

Answer 1

(1)结论就是n(n+1)(n+2)(n+3)+1=[n(n+3)+1]²

证明过程就是n(n+1)(n+2)(n+3)+1和[n(n+3)+1]²的展开式

结果都是n^4+6n^3+11n^2+6n+1

(2)20000×20001×20002×20003+1=（ 4000600001的平方）
