title: Increment value by an incrementing value and output the result
body: <p>How can I output a list of numbers, so that each next number increments by a value which in turn increments by 1 every time?</p>
  
  <p>In my case I need to output this exact list:</p>
  
  <pre><code>0
  10
  21
  33
  46
  60
  75
  91
  108
  126
  145
  165
  </code></pre>
  
  <p>So that the first value increments by 10, then the result increments by 11, then the result of it increments by 12, then by 13, 14, 15 and so on.</p>
  
  <p>I've tried to achieve this by using for-loops, but obviously haven't got any proper result.</p>
