HI Chetan - Wanted to reconfirm the rationale behind the highlighted text... 2 is a Prime No. which is even. But since 3n^2+2n+5 has the term 5, we are considering that the entire term if prime will be greater than 3 which are allodd.[/quote]

Hi
You are correct in the rationale.
Since n is a positive integer, it will be ATLEAST 1...
And when n is ATLEAST 1, the term 3n^2+2n+5 will be greater than 2...
Min value will be 3*1^2+2*1+5=10.... Thus value will be more thanOne..[/quote]

Thank You Chetan
