Was stuck, couldn't solve 
The sum of m first positive odd integers=\(m^2\)
The sum of n first positive even integers= n*(n+1)
\(m^2\)-n*(n+1)=212
Then hard times begin
I could move a bit forward:
n*(n+1) is even, as out of two consecutive integers one must be even and even multiplied by any integer is even
m must be even as only even-n*(n+1)=even
m is more than 16 as \(16^2\)= 256
Looking forward to an official solution or to an expert reply

this question does not seem to be gmat type question ...
i happened to google question its source like many of the todays post is coming from " American Mathematics Competitions."
I am not sure why Bunuel is posting questions from such sources?
Bunuel most of us are daily following your posts and solving questions which are posted by you , but questions such as the one posted if not from relevant gmat source does makes our lives difficult
, please tag such questions as out of scope so that we can atleast figure them out that they arent relevant to gmat..
