Tracing algorithms — Answer key

Work through each question. Show your reasoning where space is provided.

  1. 1. Trace this algorithm. Start x = 3. Repeat 7 times: x ← x + 22. What is the final x?

    157

    3 → 25 → 47 → 69 → 91 → 113 → 135 → 157

  2. 2. Trace this algorithm. Start x = 14. Repeat 8 times: x ← x + 28. What is the final x?

    238

    14 → 42 → 70 → 98 → 126 → 154 → 182 → 210 → 238

  3. 3. Trace this algorithm. Start x = 7. Repeat 8 times: x ← x + 7. What is the final x?

    63

    7 → 14 → 21 → 28 → 35 → 42 → 49 → 56 → 63

  4. 4. Trace this algorithm. Start x = 10. Repeat 4 times: x ← x + 6. What is the final x?

    34

    10 → 16 → 22 → 28 → 34

  5. 5. Trace this algorithm. Start x = 27. Repeat 3 times: x ← x + 9. What is the final x?

    54

    27 → 36 → 45 → 54
