Question

What is the factorial of $\left(n+1\right)$?

Answer 1

Determine the factorial of $\left(n+1\right)$.

Factorial of number $\text{'}n\text{'}$ is the product of first$n$ natural number and is represented by $n!$

$\mathit{n}\mathbf{!}\mathbf{=}\mathit{n}\left(n-1\right)\left(n-2\right)\mathbf{\dots }\mathbf{\dots }\mathbf{\dots }\mathbf{\dots }\left(3\right)\left(2\right)\left(1\right)$, where $n\in \mathrm{\mathbb{N}}$.

Calculate the factorial of $\left(n+1\right)$:

$\left(n+1\right)!=\left(n+1\right)\times n\times (n-1)\times (n-2)\times (n-3).......1$

Hence, factorial of $\left(n+1\right)$ is $\left(n+1\right)\times n\times (n-1)\times (n-2)\times (n-3).......1$.
