The sequence is

$1, 4, 16, 27, 256, 3125, 46656, 65536, 823543, 16777216, 387420489, 10000000000, 285311670611, 7625597484987, 8916100448256$

Can you figure out the pattern to this sequence of numbers?

    $\begingroup$ Just to be sure, 16 is really in this sequence? $\endgroup$

    $\begingroup$ It's a very interesting sequence, and the math behind it is fascinating, but we are somewhat picky about number sequence puzzles on this site: a puzzle whose solution can be found in the bible is not going to fare all that well. There are a couple of other hints on creating good (and bad) number sequence puzzles in the tag wiki and the linked meta question. So please do keep posting, and welcome to PSE! $\endgroup$

A quick search on OEIS give:

The Hyper-4 powers also known as Tetration

Basically:

This is a sorted list of $a^a$, $b^{b^b}$, $c^{c^{c^c}}$ and so on... where $a,b,c,...$ are Natural numbers greater than 2 (1 is the offset in this case, 1^(any number) gives 1 )
So, the next term is: 13**13 = 302875106592253

Besides 16, the sequence is

$n^n$. $1^1=1$, $2^2=4$, $3^3=27$, etc.
