1. An Order-r Total Rule Needs All r Initial Values
Use order r=2, coefficients=[1, 2] in oldest-to-newest order, constant=-2 and initial_values=[0, 1], 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. Give (order, coefficients, constant, initial_values, complete_initials, total_rule, index_scope).
View answer and explanation
(2, [1, 2], -2, [0, 1], Yes, Yes, rule_applies_for_n_ge_2)
Check coefficient/initial arity and the explicit scope n≥r. A total single-valued rule and complete initial state determine forward values; this does not prove a closed form, convergence or asymptotics. The exact result, retaining the requested order, is (2, [1, 2], -2, [0, 1], Yes, Yes, rule_applies_for_n_ge_2).
