Find the next number in the series...

8 comments:

  1. If each number in the series is multiplied by the next odd number then the answer is (1806*1807) = 3,263,442.

    However, if each number in the series is multiplied by the next prime number then the answer is (1806*1811) = 3,270,666

  4. Secret Squïrrel, the next ODD number, IS the next number (since all your answers will be even) and IS the next PRIME number (in this case).

    Anyway you look at it, you will get the same answer.
    (1806*1807) = 3,263,442

    1807
    - is the next number after 1806
    - is the next odd number
    - is the next prime number

  5. 1807 is NOT prime. 13*139=1807

    So as Lisa originally said, there are two solutions to this puzzle depending of if you use the next number, or the next prime number.
