Secuences and Other!!!
- Please forgive for my poor English but I write in my native language
and then I translate. I have solved no1 and i find it terrific and i
have not solved no2.
1)If S is the set of all the secuenses that are finally zero(a(n)=0
for all n>n0) then this set is countable and this can be shown by the
fundamental theorem of number theory(All natural numbers can be
written as a product of prime factors in an unique way)
2)If q is a prime different than 2 then there are infinite primes p
that q is the smallest prime factor of 2*p-1.
