Thanks for playing the Tuesday Brain Game. What's the next number in this sequence?

1, 2, 6, 42, 1806, ?

Here is the SOLUTION.

THE SOLUTION:

3,263,442

The formula for the sequence is Z x (Z+1) and is shows as follows:

1 x (1+1) = 2
2 x (2+1) = 6
6 x (6+1) = 42
42 x (42+1) = 1806

so the next number is:

1806 x (1806+1) = 3,263,442
