What are the next three numbers in this sequence?
6, 28, 496, 8128, ... ?
Please explain how you determined these three numbers.
It's impressive how consistently you change the subject when the truth stares at you in the face:
Penny... you remind me of Dan... ;-) a recent visitor to the site, who, like you, did everything he could to avoid the issue at hand... changing subjects and backpeddling to try and save face.
He, like you, was irked when he fell short of what he claimed to be able to do.
And yet you still haven't once answered the problem.
I suggest that you either demonstrate WHY that formula might work, or better yet, show the answer (and how you got it) without relying on Mersene primes. But, *sigh*, again [now a FIFTH time], I doubt Penny will be up to the task.
