Conversion would be ...

$\sum ^{n}_{i=1} 3^i=\frac{3^{(n+1)}-3}{2}$

There are numerous on-line examples of the proof of sums of geometric progressions by induction.

How is induction going to help? I only thought that was relevant to motors.

No induction can also be used for heating things up very quickly. I think the connection is that those crazy formulas heat up the gray-matter just as efficiently, and hence must be caused by the same fundamental effect.
