### Re: Number Theory Problem

my solution indicates \$162, 243, 324\$ and \$405\$ only, but \$605\$ is also correct(in calculator), so somewhere there could be a problem or something missed.. here it is shown the first part is, like avik da's way \$a+b+c= 9,11,19,21\$ if \$a+b+c= 9 \$then \$10a+b-8c=0..........\$..(line 1 \$a+b+c= 11 \$then \$...

### Re: Dhaka Secondary 2011/9

Yes the answer is 182 and (before posting the solution I like to thank Mahi and rafi) ....... the series is \$2+ 4+8+10+14+16+20+22+...........\$... 2011 numbers we can notice in the series the nth value is either 3n-1(n odd) or 3n-2(n even) so the 2011 th number is (3.2011-1)= 6032= 32(mod 1000) the ...

### Re: Dhaka Secondary 2011/9

yes I think this time it is okay, obviously it asks mod 3not equals 0 so, if x=(3n)^2 typed something then the mod will be 0, where 2^x will remain a remainder, and not any odd numbers of course..... and x^2 equiv 1 (mod3) when it is even,so the series should be(hope no more casualties) 2+4+8+10+14+...
