How to Extrapolate lines on Excel 2013?

[BGrewer]

For one of my assignments I have to extrapolate a line on a graph, and was wondering of anyone knows how to extrapolate lines. When searching this on the 'net the only results I get are for fitting trendlines.

Can anyone help?

Extrapolate (mathematics) - extend (a graph, curve, or range of values) by inferring unknown values from trends in the known data.

That should be all the help you need. Without the data from the question no one can help you.

So you do not want a line of best fit?

Sorry Yazen I want to extend the line. However, when I've been researching extrapolation with excel and I've only found trendlines!
Hmm... I think I need to pester my lecturer :/
