Alright.

So i'm sorry if my typing for my math equations might be off but i'm barely 5 minutes old in these forums so give me some slack. Please?

So on about factorial notation. I have no idea what it means.

Key

_ = sub

Givens:

{a_n} n=1 is defined by a_1 = 1 x 1!, a_2 = 2 x 2!,... , a_n = n x n!

C_n = a_n + a_(n + 1)

I need to write it in factorial notation. And Simplified. Any helpers out there today? =)
