A few sample questions

  1. 1. What is the only number that is both a prime number and an even number?

    Answer: 2

    2 is the only even prime number. Every other even number is divisible by 2, so they can't be prime.

  2. 2. What is the value of pi (π) rounded to two decimal places?

    Answer: 3.14

    Pi (π) equals approximately 3.14159... It represents the ratio of a circle's circumference to its diameter.

  3. 3. In the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13...), what comes after 13?

    Answer: 21

    In the Fibonacci sequence, each number is the sum of the two before it. So 8 + 13 = 21.
