They should try my Intelligence Quiz that can be found in www.easypapps.sg. And buy my book from the bookstores listed in this quiz website.
Or buy The New Paper on Sunday. It has my intelligence quiz as well.
My method also got the right answer but Mr Tan's method more logical because I cannot reason why I should add a "1" for my first calculation to get 2. Thanks for the fun.

Here is the answer to the quiz.
ReplyDeleteEach number is the multiple of the previous number and the (previous number plus 1).
For example,
1*2 = 2
2*3 = 6
6*7 = 42
42*43 = 1806
1806*1807 = 3263442
So, the 6th number in the series is 3263442.

ReplyDelete1 +
1^2(1) = 2 + 2^2(4) = 6 + 6^2(36) = 42 + 42^2(1,764) =1,806 + 1,806^2 = 3,263,442
i got it within a minute..damn it's so easy...
