Predict: I predict that I will need to use division adn addition in this problem.

Clarify: I have no words, sentences or phrases to clarify.

Find the big question: What are the two numbers?


  1. The first thing I did was divide 97 by 2= 48.5
  2. but they are consecutive whole numbers. 
  3. So I rounded up to 49. But 49+50=99, not 97.
  4. So I rounded down to 48. 48+49=97!

The answer is 97.
