I started on the Math teasers this morning - but needed caffeine to make the brain think. Thanks for waking me up. I need this type of puzzles to stay ahead of the grandkids. Hope to see more!
OK HARD FOR ME, BUT GREAT TEASER
That was a good hard one, but I must admit, I didn't even try. I was afraid my brain would crash
Actually much easier than you'd think if you just figure out what number cubed is close to the required answer, then try combinations of the consecutive prime numbers close to that number. Good teaser none the less.
I was confused at first because I misinterpreted what you meant by "consecutive primes". I was looking for three odd numbers in a row that were all prime and then the light went on in my head. (duh)I was clever enough to start looking close to the cube root, though, if that's anything to brag about.
Yeah that was REALLY Easy
I agree with stm8r1. I imagine this might be time-consuming and frustrating otherwise.
