Original question and givens

Use order r=4, coefficients=[2, 4, 6, 8] in oldest-to-newest order, constant=-2 and initial_values=[5, 6, 7, 8], where initial_values[j]=a_j. For n≥r, a_n=constant+sum over j=0..r−1 of coefficients[j]*a_(n−r+j). The state shifts left then appends the new scalar. All intermediate integer operations must be safe. Target index=8. Give (order, initial_count, target_n, target_value, unique_prefix, certificate).

  • G001 — Use order r=4, coefficients=[2, 4, 6, 8] in oldest-to-newest order, constant=-2 and initial_values=[5, 6, 7, 8], where initial_values[j]=a_j. For n≥r, a_n=constant+sum over j=0..r−1 of coefficients[j]*a_(n−r+j). The state shifts left then appends the new scalar. All intermediate integer operations must be safe. Target index=8. Give (order, initial_count, target_n, target_value, unique_prefix, certificate).

Definition and scope

Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.
