My logic was similar:<BR/><BR/>As you noted, 1+2+3+...+7+8+9 = 45, so the 4 and the 5 will have to be at the ends with a total of 36 between them, though at this point order could go either way. I'll use: 4 {36} 5<BR/><BR/>The numbers between 4 and 3 will add up to 34, which means 27 between them. What is left is 6.<BR/>4 {27} 3 {6} 5<BR/><BR/>The 2 must go closer to 4 in order for the sum of 23 to work. That puts 18 between them with 7 on the other side of 2.<BR/><BR/>4 {7} 2 {18} 3 {6} 5<BR/><BR/>And the 1 must go closer to the 3 for its sum to work: That puts 9 to the left and 8 to the right.<BR/>4 {7} 2 {9} 1 {8} 3 {6} 5<BR/><BR/>Technically there are two possible answers (472-91-8365 or 653-81-9279) but the puzzle also said that 3 is not adjacent to a dash so that eliminates the second answer.<BR/><BR/>Answer:<BR/>472-91-8365Blainehttps://www.blogger.com/profile/06379274325110866036noreply@blogger.comtag:blogger.com,1999:blog-5730391.post-12427064781185025802008-06-12T05:21:00.000-07:002008-06-12T05:21:00.000-07:00Here goes:If I pick 4 as the first digit and 5 as ...Here goes:<BR/><BR/>If I pick 4 as the first digit and 5 as the last digit:<BR/><BR/>4xx-xx-xxx5<BR/><BR/>4xx-xx-x365 fits the 34 clue<BR/><BR/>472-91-8365 then fits the remainder clues.Don Hodunhttps://www.blogger.com/profile/10629317119387671011noreply@blogger.comtag:blogger.com,1999:blog-5730391.post-12220581104573034652008-06-12T05:14:00.000-07:002008-06-12T05:14:00.000-07:00Blaine, I guess that helps.

I found a sequence that fit 3 of the 4 criteria, but did not limit the placement of 4 and 5 as your reply did.Don Hodunhttps://www.blogger.com/profile/10629317119387671011noreply@blogger.comtag:blogger.com,1999:blog-5730391.post-35215262788894391392008-06-11T16:02:00.000-07:002008-06-11T16:02:00.000-07:00Don, consider 1 and 2 the end points of a sequence...Don, consider 1 and 2 the end points of a sequence of digits (e.g. 2451). That sequence adds up to 12. If you can arrange all 9 digits to meet the criteria, you've found the number.Blainehttps://www.blogger.com/profile/06379274325110866036noreply@blogger.comtag:blogger.com,1999:blog-5730391.post-31816362225519276232008-06-10T17:27:00.000-07:002008-06-10T17:27:00.000-07:00Don, under your interpretation is the solution uni...Don, under your interpretation is the solution unique?Erichttps://www.blogger.com/profile/00478789589953835840noreply@blogger.comtag:blogger.com,1999:blog-5730391.post-62493923050169651442008-06-09T12:36:00.000-07:002008-06-09T12:36:00.000-07:00Blaine, I assume that when you talk about the digi...Blaine, I assume that when you talk about the digits from 4 to 5 inclusive, a number like xyz54abcd encompasses all of the digits, i.e., you count from L to R only??Don Hodunhttps://www.blogger.com/profile/10629317119387671011noreply@blogger.comtag:blogger.com,1999:blog-5730391.post-3360715273875005612008-06-08T11:31:00.000-07:002008-06-08T11:31:00.000-07:00The answer is the product of the following primes:...The answer is the product of the following primes:<BR/> <BR/>3 x 3 x 3 x 5 x 3503099Joe Whttps://www.blogger.com/profile/18115545643638113334noreply@blogger.com
