You can put this solution on YOUR website!
In the formula, substitute the value for n and simplify,
S%28n%29=%28n%28n%2B1%29%282n%2B1%29%29%2F6
When n=1,
S%281%29=%281%281%2B1%29%282%281%29%2B1%29%29%2F6+
S%281%29=%28%281%29%282%29%283%29%29%2F6=6%2F6=1
.
.
.
When n=2,
S%282%29=%282%282%2B1%29%282%282%29%2B1%29%29%2F6
S%282%29=%282%283%29%285%29%29%2F6=30%2F6=5
.
.
.
When n=3,
S%283%29=%283%283%2B1%29%282%283%29%2B1%29%29%2F6
s%283%29=%282%284%29%287%29%29=56%2F6=28%2F3
.
