$\begingroup$ Might want to include where you got the puzzle since (based on the screenshot) you did not create it yourself. $\endgroup$– JGibbersCommented Oct 10, 2018 at 18:16

$\begingroup$ This is interesting, because I have seen both your puzzle as well as the one below by searching online. Here is an example of mine and another; here is an example of yours. Indeed, there seems to be a variety of "puzzles", as here's another variation. All of them "come from IBM aptitude tests". $\endgroup$– El-GuestCommented Oct 10, 2018 at 18:22

I think there might be a few typos, because it looks like the pattern is
$6^5$, $5^4$, $4^3$, $3^2$, which means the next number is $2^1 = 2$.
The pattern (if this is correct) is then
7776, 625, 64, 9, 2
