|For those people who don't know what a triangular number is, http://mathworld.wolfram.com/TriangularNumber.html is a very nice introduction (helped me anyway).|

|wow...the hardest teaser on the site|
|Posted by darthforman||05/11/05|
| :( it IS the hardest...
|Posted by KimOHara||05/21/05|
|I got the triangular part right away, but couldn't get the other part... the EASY part, now that I know what it was!|

|i got the palindromic triangle part, but dont know how to figure out triangle numbers, and wasnt sitting there for a LONG LONG time doing them and checking for palindrom-icity (yes, i made that word up)|

|i didnt get it :cry:|

|WOW! THAT IS HARD! :roll: :( :cry:|

|I realized they were all triangular numbers but couldn't figure out the correlation between them.
Nice teaser, I don't think it is so hard. :D|

| :roll: Orangutans forced to watch Days Of Our Lives could have aced that one. Try and think of something harder next time. :roll:|

|I got the palindrome part, ( Didnt everyone :lol: ) But I didnt see the triangular part right away.This was very hard!|

|WOW!, needed 2nd cup of coffee and 40yrs of memory back to high school, but it finally came to me GREAT JOB 8)|

|con grats on the hardest teaser
p.s. did any one get it right|
|Posted by smarty_blondy||11/07/05|
|Hardest one on site? I got this one right away as i knew half of them and so i got the pattern. Only had to do a bit of googling for the missing ones. I will admit it's brilliant though, good job! :D|

don't get it...

|I got tha palindrome part but only got the triangular number part after the hint|

|Heh .. I was trying to work out a pattern before I realized they were palindromic.
corresonds with 1,2,3,10,11,18...
Okay, maybe it's 123, 123... 1+0=1... 1+1= 2... 1+8=.. damn.
Didn't want to go down the line calculating.. so I googled palindromic triangular numbers :P|

|Easy, just simple....Not its the hardest one here :-?|

|what's a triangular number?
|Posted by javaguru||01/08/09|
|Took longer to figure out what the next three palindromic triangular numbers were than it did to figure out the rule.
Pretty nice teaser, but not terribly difficult.

|I don't understand why this one is rated so difficult?|
|Posted by krishnan||09/01/10|
|Nice, fun teaser, got the answer as soon as I saw 55 and 66.|
