Well, i am stuck with a problem. I have to prove that 7|(3^(2n+1) + 2^(n+2)) using the modulo m congruency.
Well this will mean that 3^(2n+1) + 2(n+2) mod 7 = 0, but i cant find a whay to prove the initial expression.
Any ideeas?
Thanks

Thanks, i will give it a try.
I will post a little later what i have succeded to solve. And if you will have some free time i will ask you to look at it.
Thanks again.
