Secret Squïrrel said...: 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; June 9, 2009 4:59 PM

Widad said...: 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; October 15, 2009 12:52 AM
