Input number of elements to be printed at start

Answer 2

Formula:
x * (( 0.5x ) + 0.5 )

Where x is the n'th number, starting at 1.

Example:
3 * ((0.5 * 3) + 0.5)
= 3 * (1.5+0.5)
= 3 * 2
= 6
3rd number is 6.

One possible way

Answer 4

Since everyone is posting solutions, here is one using a generator:

Nevertheless, you probably should have tried to solve that yourself.

Answer 5

int outputs = [];
const arrSize = 100;

for (i=0,a=0;a <arrSize;a++) {
i +=a+1;
outputs [a] = i:
}

Answer 6

using C++

#include <iostream>

using namespace std;

int main()
{

int a = 0;

for (int i = 1; i < 100; i++)
{
a += i;
cout << a << " ";

}

system("pause");
return 0;
}

using C#

using System;

namespace soloApp
{
class Program
{
static void Main(string[] args)
{
int a = 0;

for (int i = 1; i < 100; i++)
{
a += i;
Console.Write(a + " ");

}
}
}
}
