### Finally back! Need help on this advanced algebra problem.

(a) Determine all nonnegative integers \$r\$ such that it is possible for an infinite arithmetic sequence to contain exactly \$r\$ terms that are integers. Prove your answer.

(b) Determine all nonnegative integers \$r\$ such that it is possible for an infinite geometric sequence to contain exactly \$r\$ terms that are integers. Prove your answer.

I know this problem may have been answered before, but I didn't find those explanatory enough. If you can find a thorough resource, refer me to that, please. Otherwise, solve it here.
