Question 4896: Inclusive Natural Successor Window

Original question and givens

N includes 0. n=19, k=2. List the complete ordered window beginning at n and applying the successor k times.

• G001 — N includes 0. n=19, k=2. List the complete ordered window beginning at n and applying the successor k times.

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.

Step-by-step derivation

N={0,1,2,...}

0 belongs;negative and nonintegral rational values do not

initial n=19;successor count k=2

[19]

successor step1 := sum(19, 1)

successor step1 = 20

successor step2 := sum(20, 1)

successor step2 = 21

Reverse checks

• S005 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
• S004 · premise_and_result_audit — Recompute successor step2 with exact rational arithmetic, not rounded decimals.
• S003 · premise_and_result_audit — Recompute successor step1 with exact rational arithmetic, not rounded decimals.
• S002 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
• S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.

Result

[19, 20, 21]

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
