title: Extrapolating values into the future
body: <p>I have set of data as follows:</p>
  
  <p><pre><code>1/3/15 245
  2/3/15 246
  3/3/15 260
  4/3/15 261
  5/3/15 267
  6/3/15 270
  7/3/15 278
  8/3/15 290
  9/3/15 314
  </pre></code></p>
  
  <p>With the values corresponding to the dates, (<strong>Q:</strong>) how can I predict what date the values; 350, 400, 450, 500, 550 and 600 will correspond to?</p>
  
  <p><em>Further note:</em>
  I have graphed these values, got a linear (y=mx+b) trend line, and tried to 'calculate' the dates. Is there another/alternative method? I have been using Excel 2013.</p>
