There happens to be a politician that might lie at any moment (this isn't unusual) but his conscience bothers him enough (now, that is unusual!) so he won't say two lies in a row.

He said ten consecutive statements.

How many combinations of truths/lies can there be?

Excellent!

Can't the nth Fibonacci number be gotten in 1 step, rather than a number proportional to log(n)?:

F(n)=[(phi^n)/sqrt(5)+.5], where [] represents the floor function, so that [ +.5] represents rounding to the nearest integer, and phi is the golden ratio.

(I tried using the square root symbol in the new editor, but got garbage.  I also tried viewing source and pasting in the ampersand code for phi, but that didn't work either.)
