    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.

    37 seconds

    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
