"Compute the first few terms and plug into OEIS" is very high on the reward:effort scale
not really solving the problem though. would be easier to directly search for project euler xx solution.
Came here to say this-- I've solved a lot of otherwise seemingly quite hard problems by numerically/brute-force finding the first few terms then asking OEIS then convincing myself it it's indeed the solution.
