Answer today's ISEE Middle Level Mathematics Achievement question, reveal the full explanation, then keep the streak going with a new question every day.

What is the next term in the pattern: 100, 99, 96, 91, 84, ...?

  1. 77
  2. 76
  3. 75 (correct answer)
  4. 73

Explanation: The differences between consecutive terms are increasing. The differences are: 100−99=1100 - 99 = 1, 99−96=399 - 96 = 3, 96−91=596 - 91 = 5, 91−84=791 - 84 = 7. The amounts being subtracted are consecutive odd numbers. The next odd number to subtract is 9. Therefore, the next term is 84−9=7584 - 9 = 75.
