This first one is bike-related, but many won't be, so this is probably the appropriate forum.
e.g. 2011 is the sum of 11 *consecutive* primes. I'll leave figuring out which they are as an exercise for the class, with the hint that the final one is suggestive.
If you'd planned ahead you could have had the trip meter reading 7777 as well.
Heh, I struggle to plan 20 min ahead, so 6 months or so is right out of the question!
I never get these... don't see the pattern ](*,)
There isn't one. That's what makes prime numbers interesting and why, in spite of centuries of trying, noone has yet come up with a means of generating primes that will work in all cases.
You don't need a pattern.
I divided 2011 by 11, to get the average value of each prime: 182.82...
I then chose the 5 primes either side of the one nearest the average (181).
spacial (sp?) maths and mechanics I understand, that I don't :shrug:
...I'm going to look at something shiny now...
