k列的经验值：
k=1:a（n）=2*a（n-1）-a（n-3）
k=2:a（n）=6*a（n-1）-9*a
k=3:a（n）=9*a（n-1）-24*a（n-2）+9*a
k=4:a（n）=12*a（n-1）-43*a
k=5:[顺序7]
k=6:[顺序9]
k=7:[顺序9]
第n行的经验值：
n=1:a（n）=n+1
n=2:a（n）=n^2+2*n+1
n=3:a（n）=n^3+3*n^2+3*n+1
n=4:a（n）=n^4+4*n^3+6*n^2+2*n+1
n=5:a（n）=n^5+5*n^4+10*n^3+4*n^2+3*n+1
n=6:a（n）=n^6+6*n^5+15*n^4+8*n^3+5*n^2+6*n-1
n=7:a（n）=n^7+7*n^6+21*n^5+15*n^4+7*n ^3+17*n^2-n-1
