COMMENTS
| This is the special case k=1 of sequences with mutual residues -k. In general, a(1)=k+1 and a(n)=min{m | m>a(n-1), mod(m,a(i))=-k, i=1,...,n-1}.
An infinite coprime sequence
Same as A005267 but two first terms in reverse order

FORMULA
| a(1)=2, a(2)=3, a(n)=-1+a(1)*a(2)*...*a(n-1)
a(n)=a(n-1)^2+a(n-1)-1, n>3

|
MAPLE
| a:=proc(k, n::nonnegint) option remember; if n<3 then RETURN(n*k+1); fi; if n=3 then RETURN(a(k, 1)*a(k, 2)-k); fi; a(k, n-1)*(a(k, n-1)+k)-k; end; seq(a(1, n), n=1..10);
