I know this is not a math forum, but I am so desperate, and I know there are lots of smart people on here. I have this math assignment and I can't do it! It'd due tomorrow too -_-;; Anyway, if anyone can solve this, please, please, let me know, thank you:

Cn=A(n)+A(n+1) -- A=kxk!
=nxn!+(n+1)(n+1)!
=n!(n^2+3n+1)

Tn=C1+C2+C3+...+Cn
Conjecture an expression for Tn.

I can't do it X_X

Sorry for the delay. Took some time to post this and get someone
to answer. This is ygfperson's conjecture:

Tn = sum of C(1) to C(n)

Cn = a(n) + a(n+1)
a(n) = n*n!
C1 = a(1) + a(2)
C2 = a(2) + a(3)
Tn = a(1) + 2a(2) + 2a(3) + ... + a(n+1)
Tn = 1 + 8 + 36 + ... + (n+1)*(n+1)!

Hope it's a help.
