It takes me about 25 seconds to solve it!? I'm smarter than Einstein!? O.O"
The answer is 3263442.
Solution is pretty simple, just multiply the number with 1 unit larger than it will be the next number. Generally, it is:
"(Previous number)*(Previous number + 1), which apply for 2nd and following terms, and the first term is 1."
For example:
1st term = 1 (Given)
2nd term = 2 (Which is 1*2=2)
3rd term = 6 (Which is 2*3=6)
4th term = 42 (Which is 6*7=42)
5th term = 1806 (Which is 42*43=1806)
Hence,
6th term = 1806*1807 = 3263442 [Solved]
LOL, however it takes me 10++ minutes to type all this sh*t.

It is a well-known sequence, where each number in the sequence is the square of the number before it, plus that number.
1^2+1=2
2^2+2=6
6^2+6=42
