Just as valid.  I could tell  you the rule if youwere interested, but most folks are not.

Rule: Given a finite number of term in A sequence, there are INFINITELY many extensions of that sequence.  It is wholly and painfully inappropriate to state, "Find THE next three terms of THE sequence. Then write a rule for THE sequence."  It would be FAR more appropriate to state: "Find a formula that will reproduce this sequence and continue this sequence for three more terms.  Justify your answer."
