no

you can look for funny patterns

7 - 3 = 4

13 - 7 = 6

27 - 13 = 14

33 - 27 = 6

\Rightarrow

\dots 4, 6, 14, 6, 4, 6, 14, 6, 4, 6, 14, 6, \dots

\Rightarrow x = - 3 \land y = 37

or

\dots - 16, 6, - 6, 6, 4, 6, 14, 6, 24, 6, 34, 6, \dots

\Rightarrow x = - 3 \land y = 57

or find a polynome for the given numbers

a_{n} = - \frac{11}{12} n^{4} + \frac{61}{6} n^{3} - \frac{445}{12} n^{2} + \frac{347}{6} n - 27

\Rightarrow x = - 27 \land y = - 7

\dots

3 + 10 = 13

13 + 20 = 33

S i m i l a r l y,

- 3 + 10 = 7

7 + 20 = 27

27 + 30 = 57

∴ x = - 3

y = 57
