The only thing i got was
5/2n^2 + 8n + 7/4
((n^2+(n+1)^2)/4) + 3 [(1/6)n(n+1)(2n+1)] + 2 [(1/2)n(n+1)]
After putting all the terms to a common denominator. Then expanding out, and simplifying the above I get
((12n^3+36n^2+14n+1)) / 12
And I need to get
(1/4)n(n+1)(n+2)(n+3)
Can someone help the simple further steps to take thanks :-)
