Maths & Logic

This shouldn't take long if you're good at logical problems...

What is the missing number in this logical series?

1, 2, 6, 42, 1806, ____???

3263442

here's how I worked it out,

I started backwards..

1806 / 42 = 43

This led me to notice a pattern:

Take the number and multiply with the number that comes after it.

1 (times 2) 2 (2 times 3 ) 6 (6 times 7) 42 .......etc....

Jazakillah for posting this.

Sorry for the late response.
