Probing questions
I know a secret sequence. It has these numbers in it: 13, 15, 17, 19.
What numbers come next in my sequence? What numbers come before? What clues did you use to work this out? Give me a number that is greater than 50 that is in my secret sequence. Tell me how you know this number is in my sequence. How could you
check? Is 64 in the sequence? How do you know?
Use similar questions for a range of sequences.
