How can I use the following formula to determine the value of a variable?
Before someone suggests this is off topic, I am not on Stack-overflow to determine what formula to use. I am here so I can figure out how to utilise the formula via c#.
Background:
I had previously opened a thread on math.stackexchange.com so someone there could help me generate a forumla which would create the following sequence: 1 , 7 , 14, 30. A user there called "Half-Blood prince" suggested I use the below formula to generate this sequence
an=A*n^3+B*n^2+C*n+D
I have in the past used int, double etc. then within a loop say int i = i*7; but obviously in this case the mathematical forumla is alittle more complicated, so I'm here to ask how can I utilise the above whithin C#

You could use that equation in C# like so:
public static double Calculate(double n)
{
return (1.33*(n*n*n)) - (7.5 * (n*n)) + (19.16 * n) - 12;
}
And call it with
Console.WriteLine(Calculate(1));
Console.WriteLine(Calculate(2));
Console.WriteLine(Calculate(3));
Console.WriteLine(Calculate(4));
The above writes
0.99
6.96
13.89
29.76
Which is your required sequence, if you rounded each result to an integer.
