Question

Can you write a summation notation of a series that is neither arithmetic nor geometric?

Answer 1

Answer:

Yes, we can.

Step-by-step explanation:

Hello, I found this one.

$\displaystyle \sum_{n=0}^{\infty} \dfrac{1}{n!}$

We can prove that it exists and it is equal to e.

But this is nor arithmetic nor geometric.

Thank you
