Number Series Practice

How to approach it

Number series test arithmetic structure, not advanced mathematics.

Work accurately before quickly. State the rule, test every step, then compare choices.

Practice set

Try each prompt before reading its answer or strategy.

• 4, 7, 10, 13, ? — 16.
• 2, 6, 18, 54, ? — 162.
• 9, 16, 25, 36, ? — 49.
• 20, 18, 19, 17, 18, ? — 16.
• 3, 4, 6, 9, 13, ? — 18.
• 96, 48, 24, 12, ? — 6.

Practice effects

Practice improves familiarity and strategy, but a short exercise is not a standardized assessment.

Use unfamiliar material and time between sessions for a more honest snapshot.
