Callipygous Posted January 21, 2006 Posted January 21, 2006 the tag for spoiler is [hide] why is that the answer? didnt you say primes? 9 isnt prime... im lost
NPK Posted January 21, 2006 Author Posted January 21, 2006 [hide]there are 2 patterns interwoven - the first pattern (1st, 3rd, 5th etc. numbers) starts at 10 and adds the next prime number after 10. So add 11 to get 21; add 13 to get 34; add 17 to get 51; add 19 to get 70; add 23 to get 93. The second pattern (2nd, 4th etc numbers) are simply the reverse of the preceding number. Hope that makes sense! [/hide]
Callipygous Posted January 21, 2006 Posted January 21, 2006 gotcha... [hide]i was confused because the first digits of the first set of numbers also happen to be the primes. 1,2,3,5,7...[/hide]
