**I have a tricky question here....**

I have been asked to compare the formulae of Sygma (k=1 until n value) of k, Sygma (k=1 until n value) of k(k+1) and Sygma (k=1 until n value) of k(k+1)(k+2)?

Hence comparing these...

Sygma (k=1 until n value) of k =

**1/2 n(n+1)**

Sygma (k=1 until n value) of k(k+1) =

**1/3 n(n+1)(n+2)**

Sygma (k=1 until n value) of k(k+1)(k+2) =

**1/4 n(n+1)(n+2)(n+3)**

**I have been asked to comment on these as much as I possibly can??? Can anyone help?**
