Adding them and multiplying them .

But what do we have to do next ? - Jul 27th 2012, 12:48 PMHallsofIvyRe: Finding a_2012
Have you tried just calculating $\displaystyle a_1$, $\displaystyle a_2$, $\displaystyle a_3$, ...?

How? you mean to set n=2011

I mean exactly what I said! Calculate as many of $\displaystyle a_1$, $\displaystyle a_2$, $\displaystyle a_3$,... as required until it dawns on you!
