If the answer is 7 digits starting with 3 and ending with 2 then i've got it I think in which case I'll leave it for someone else

It's a pretty simple pattern but I'll also leave the answer for others.

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.
