Thread: Simplified Factorial Notation

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? =)

If , then it would follow that

So,

Does this make sense?

Alright the last part is also what I have but is it all the way simplified.

I also forgot to include that a_n can also be expressed as (n + 1)! - n!.

Could you also give me a link on how you guys right it as neatly as you guys do? It looks so much better then my typing =).

These formulas are written using LaTex coding. There is a section in here that may help:
