1$\begingroup$ What are the first two numbers? Did you mean to not reveal them by putting dashes? $\endgroup$– Wais KamalSep 9, 2018 at 17:03

$\begingroup$ Yes they are meant to be hidden. $\endgroup$– SimdSep 9, 2018 at 17:06

$\begingroup$ Just as a suggestion, you should post questions not too often (once or twice a day is fine) so that you can put more effort into making it. You can also combine multiple puzzles into one if they are related :D $\endgroup$– Kevin LSep 10, 2018 at 4:33

Given that the last two numbers can be formed by
$ 4 + 6 + 3 = 13 $ (summing visible number #1, #3, #5)
$ 3 + 6 + 13 = 22 $ (summing visible number #2, #4, #6)
My answer for the next number is
$ 6 + 3 + 22 = 31 $ (summing visible number #3, #5, #7)
This would mean that the first two numbers are the solutions to
$ a + 4 + 6 = 6 \implies a = -4 $
$ b + 3 + 6 = 3 \implies b = -6 $

1$\begingroup$ That means the first and second invisible numbers are Rot13(artngvir sbhe naq artngvir guerr, erfcrpgviryl), assuming you are correct (which I am certain you are) :P $\endgroup$– Mr PieSep 11, 2018 at 12:29
