[Resource] Factoring + Is Integer + Is Prime
Chrono:
--- Code: ---function mSumSeries(%n,%f,%d)
{
//n = number of terms
//f = first term
//d = difference
return %n/2*((2*%f)+(%n-1)*%d);
}
--- End code ---
ex:
mSumSeries(5,1,1); = 1+2+3+4+5 = 15
mSumSeries(4,2,1); = 2+3+4+5 = 14
mSumSeries(3,1,2); = 1+3+5 = 9

nvm, will ask in seperate topic
