R0008-04891 · q-20261008-advance-20261011-r01-natural-number-0016

Original question and givens

N includes 0. n=14, k=6. List the complete ordered window beginning at n and applying the successor k times.

  • G001 — N includes 0. n=14, k=6. 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

S001 · implies

Before

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

After

0 belongs;negative and nonintegral rational values do not

Conditions: none

This convention includes0 in N;distinguish membership,rational values,partial predecessors and closed intervals.

Step identifiers and dependencies

Rule: natural_zero_convention · Uses: G001

S002 · implies

Before

initial n=14;successor count k=6

After

[14]

Conditions: none

Include the initial point;even k=0 has one item.Do not apply a successor before starting the list.

Step identifiers and dependencies

Rule: successor_window_initial · Uses: G001, S001

S003 · calculation

Before

successor step1 := sum(14, 1)

After

successor step1 = 15

Conditions: none

Add1 to the preceding natural at each step.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S002

S004 · calculation

Before

successor step2 := sum(15, 1)

After

successor step2 = 16

Conditions: none

Add1 to the preceding natural at each step.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S003

Before

successor step3 := sum(16, 1)

After

successor step3 = 17

Conditions: none

Add1 to the preceding natural at each step.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S004

S006 · calculation

Before

successor step4 := sum(17, 1)

After

successor step4 = 18

Conditions: none

Add1 to the preceding natural at each step.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S005

S007 · calculation

Before

successor step5 := sum(18, 1)

After

successor step5 = 19

Conditions: none

Add1 to the preceding natural at each step.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S006

S008 · calculation

Before

successor step6 := sum(19, 1)

After

successor step6 = 20

Conditions: none

Add1 to the preceding natural at each step.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S007

S009 · implies

Before

[14, 15, 16, 17, 18, 19, 20]

After

6 successors and 7 total entries

Conditions: none

Applying k successors produces k+1 entries,retaining the full order and initial point.

Step identifiers and dependencies

Rule: successor_window_length · Uses: G001, S008

Reverse checks

  • S009 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
  • S008 · premise_and_result_audit — Recompute successor step6 with exact rational arithmetic, not rounded decimals.
  • S007 · premise_and_result_audit — Recompute successor step5 with exact rational arithmetic, not rounded decimals.
  • S006 · premise_and_result_audit — Recompute successor step4 with exact rational arithmetic, not rounded decimals.
  • S005 · premise_and_result_audit — Recompute successor step3 with exact rational arithmetic, not rounded decimals.
  • 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

[14, 15, 16, 17, 18, 19, 20]

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