|Fairly obvious?||2||19:18, 23 March 2012|
I don't think it is helpful to say <<for fairly obvious reasons>> without mentioning these so obvious reasons.
Also, a key idea is that b_n is decreasing. The hint should hint to this fact.
I'll restate the hint and add another hint for the fact that bn is decreasing.
