Question of the Day

Answer today's ISEE Lower Level Quantitative Reasoning question, reveal the full explanation, then keep the streak going with a new question every day.

What number completes the sequence: 8 12 16 20 __?

  1. 21
  2. 24 (correct answer)
  3. 20
  4. 28

Explanation: This question tests ISEE Lower Level quantitative reasoning skills: finding a missing term in a sequence. Understanding sequences involves identifying the pattern that determines each term. In this question, the sequence follows a pattern of adding 4 to each term (8+4=12, 12+4=16, 16+4=20). The correct answer is 24 because it continues the pattern of adding 4 to the previous term (20+4=24). Choice A (21) is incorrect because it fails to apply the pattern consistently and demonstrates a common error of adding only 1 instead of 4. To help students: Practice recognizing arithmetic and geometric patterns. Use number lines to visualize basic sequences.
